Every purchase order rests on a human being. On any given day in 2021,
an estimated 49.6 million people worldwide were living in modern slavery,
including 27.6 million in forced labour, according to the International Labour
Organisation, Walk Free and the International Organisation for Migration.
Behind contracts, factories and shipments are workers whose conditions may be
invisible to the organisation benefiting from their labour. Ethical sourcing
asks a blunt question: how confidently can any buyer say its value was not
extracted through exploitation?
Globalisation has built supply networks of extraordinary depth. A
buyer may know its immediate supplier intimately while knowing almost nothing
about the farms, mines, processors and labour agencies operating three or four
tiers upstream. Forced labour, child labour and unsafe conditions can hide
behind apparently reputable brands. The ILO estimates such exploitation
generates around US$236 billion, roughly £175 billion at current exchange
rates, in illegal profits every year — money stolen directly from workers’
wages.
A signed code of conduct does not answer this question. It records an
intention, not a fact. Modern slavery statements and supplier declarations
establish what an organisation expects; they cannot, on their own, establish
what is actually happening on a farm or in a workshop several contracts removed
from the buyer. Procurement’s task is to convert declarations into evidence —
to know the difference between a supplier saying the right thing and a worker
experiencing it.
No organisation can inspect every workplace in its supply chain, and
few possess the commercial leverage to control conditions across sprawling
international networks. The 2024 Global Slavery Index estimates that G20
countries import US$468 billion of at-risk goods annually — electronics,
garments, palm oil, cocoa and solar panels prominent among them. Realistic
ethical sourcing therefore means directing scrutiny towards the categories,
geographies and workforces where the evidence of risk is strongest, rather than
promising uniform certainty everywhere.
Procurement alone cannot end forced or child labour, but every purchasing decision either reinforces exploitative conditions or resists them. Price, lead time, contractual terms and willingness to fund remediation all matter. The test of ethical sourcing is not how a policy reads in a boardroom, but whether it still shapes a purchasing decision when protecting workers costs money, time or a valued supplier relationship.
When Low Prices Conceal a Human Cost
Global sourcing has cut costs and widened choice by opening markets
that were once inaccessible. That efficiency can mask a darker ledger. Behind a
competitively priced contract may sit workers facing excessive hours, withheld
wages, debt bondage or forced labour. The ILO’s 2024 estimates put the average
illegal profit extracted per forced labour victim at around US$10,000 (roughly
£7,400) a year — money that should have been a wage, not a windfall for an
exploiter.
Exploitation rarely surfaces in the relationship between a buyer and
its direct supplier. It tends to occur further upstream, where raw materials
are grown, extracted or first processed. Each additional tier adds distance
between a purchasing decision and the person affected by it. In cocoa, coffee,
cotton and minerals, that distance can span several countries and dozens of
intermediaries before a recognisable, branded product ever reaches a UK shelf.
A Tier 1 supplier can pass every check an organisation runs —
financial due diligence, a signed code of conduct, a modern slavery statement —
while itself sourcing materials or labour from businesses whose practices would
be unacceptable to the end customer. Responsible behaviour at the point of
contract says nothing about behaviour three tiers back. Assurance built solely
on the immediate supplier relationship therefore measures the wrong thing.
A single manufactured product can incorporate raw materials,
components and processing activity from numerous countries and businesses
simultaneously. Contractors subcontract, subcontractors engage labour agencies,
and commodity traders aggregate materials from many small producers before
anything reaches a recognisable brand. Knowing the identity of the contractual
supplier therefore does not reliably tell a procurement team who actually
produced what the organisation is buying, or under what conditions that
production took place.

Case Study: Leicester’s Garment Factories In 2020, investigations into
Leicester’s garment sector — which supplies UK high-street and online fashion
retailers, including Boohoo — found workers paid as little as £3.50 to £4 an
hour, less than half the National Minimum Wage then in force (£8.72). A 2022
survey of 116 Leicester garment workers, commissioned in the scandal’s
aftermath, found 56 per cent still paid below minimum wage, 55 per cent
without holiday pay and around a third with no contract or payslip. The
National Crime Agency opened a modern slavery investigation into the sector.
The case is a reminder that exploitation risk sits within UK domestic supply
chains, not only overseas. |
Commercial pressure compounds the risk. Buyers routinely demand lower
prices, shorter lead times and rapid responses to shifting demand, and
suppliers operating on thin margins often pass that pressure straight down
their own supply chains. An organisation cannot credibly demand fair wages and
reasonable hours from a factory while simultaneously setting prices or
deadlines that make lawful employment practices commercially unviable for
whoever ultimately does the work.
Ethical sourcing therefore has to move well beyond a modern slavery
clause buried in a contract schedule. It requires organisations to identify
where the human rights risk actually sits, decide how far to investigate, and
build verification proportionate to what is at stake. Supplier questionnaires
have value as a starting point, but on their own they confirm paperwork, not
welfare. Mapping, worker engagement, independent evidence and targeted audits
carry the weight that declarations alone cannot.
Discovering an unethical supplier is not, by itself, a solution.
Terminating a contract overnight can strip income from already vulnerable
workers without correcting the practice that harmed them, and can push the same
exploitation towards a less scrupulous buyer. The more useful distinction is
between deliberate abuse, which usually warrants exit, and inadequate control
that a willing supplier can be helped to fix through a costed, time-bound
corrective plan.
Visibility, influence and evidence define the limits of what
procurement can achieve. No buyer can personally inspect every farm or factory
connected to its spend, but foreseeable risk left uninvestigated is difficult
to defend once something goes wrong. Effective sourcing channels scrutiny
towards where vulnerability is greatest, and aligns contractual terms,
purchasing behaviour and escalation processes so they reinforce each other
rather than quietly working against one another.
A zero-tolerance policy is only as credible as the organisation’s
willingness to act on inconvenient evidence. Investigating beyond a comfortable
supplier assurance, querying an established relationship, and taking
proportionate action when a serious risk surfaces — even where it carries cost
or reputational exposure — is what separates a working ethical sourcing
programme from a well-worded document that nobody tests.
The honest position is that procurement cannot guarantee every worker in a fragmented international network is treated fairly; in the most complex chains, absolute certainty is not achievable. What can reasonably be expected is that an organisation understands its material human rights risks, investigates them with intent, uses whatever leverage it has, and responds credibly when concerns are raised — starting with its direct suppliers, but rarely ending there.
What Is Ethical Sourcing?
Ethical sourcing is the deliberate weighing of human rights and social
conditions alongside price, quality and delivery in every purchasing decision.
It asks whether commercial value has been achieved without transferring
unacceptable costs onto the people who produced it — the workers, communities
and vulnerable groups who sit furthest from the buyer’s boardroom but closest
to the actual point of production, extraction or assembly.
Legal compliance sets a floor, not a ceiling. A supplier can meet
every requirement of local law while still falling well short of
internationally recognised standards on wages, hours, freedom of association or
safety. The gap matters most in countries where statutory protection is weak or
poorly enforced; the UK’s National Living Wage of £12.21 an hour (Apr 2026) for
workers 21 and over is, by international comparison, a demanding benchmark that
many overseas jurisdictions do not require or enforce.
Human rights sit at the centre of ethical sourcing because the
consequences of failure are severe and frequently irreversible. Particular
vigilance is warranted around forced labour, child labour, debt bondage,
recruitment fees, passport retention and restrictions on a worker’s freedom to
leave employment — risks that typically surface several contractual
relationships removed from the organisation that ultimately places the order.
Ethical sourcing nevertheless extends beyond labour conditions alone.
It can encompass environmental protection, responsible mineral extraction,
anti-corruption controls, equality and community impact, with priorities
varying by sector and category. Human rights warrant particular weight
regardless of category, however, because the people affected typically have the
least bargaining power and the fewest realistic routes to escape or challenge
the conditions imposed on them.
Ethical sourcing is a narrower discipline than ethical procurement,
which concerns the integrity of the buying process itself — competition,
conflicts of interest, bribery and professional conduct. A competitive tender
run with complete procedural integrity can still deliver an ethically
compromised supply chain if nobody examines what happens once the ink is dry
and production actually begins several tiers upstream.
It is equally distinct from sustainable procurement, which typically
weighs environmental, social and economic outcomes together across a purchase’s
full lifecycle. A product can carry strong environmental credentials — recycled
content, low carbon transport — while still incorporating materials linked to
exploitative labour. Environmental performance is not evidence, on its own,
that the people who made the product were treated fairly.
Effective ethical sourcing starts before a contract is signed.
Procurement teams should identify which categories carry elevated human rights
exposure, understand the relevant country and commodity risk, and specify what
evidence a bidder must supply. Building this into specifications and evaluation
criteria embeds ethical performance as a genuine commercial requirement, rather
than an afterthought bolted on once price and supplier selection have
effectively already been decided.
Risk proportionality keeps the system workable. Applying identical
scrutiny to office stationery and garments manufactured through several Asian
subcontractors wastes effort on the former and under-resources the latter.
Prioritising by severity, likelihood, geography and workforce vulnerability
lets a finite compliance team concentrate on cocoa, coffee, garments, seafood,
electronics and construction — the categories the Global Slavery Index and Home
Office both flag as highest risk.
Declarations remain a reasonable starting point but a poor finishing
line. Codes of conduct and modern slavery statements demonstrate that
expectations were communicated; they cannot demonstrate that anyone met them.
Stronger assurance draws on payroll records, recruitment documentation, worker
interviews, independent audits and traceability data, with the intensity of
evidence rising in step with the severity of the harm being tested against.
Visibility and verification answer different questions and are
frequently confused. Mapping identifies who participates in a supply chain;
verification establishes whether those participants comply with required
standards. An organisation can successfully name a Tier 3 manufacturer while
having no idea whether its workers are paid correctly or employed voluntarily —
precision about who exists in a chain is not the same as evidence about how
that chain actually treats people.
Due diligence does not end at contract signature. Risk profiles shift
when a supplier restructures, adds a subcontractor, enters a new country or
comes under sudden financial pressure. Continuing engagement, defined
escalation triggers and periodic re-assessment matter as much as the original
tender evaluation, because a supply chain judged low-risk at award can look
materially different eighteen months into delivery.
Ultimately, ethical sourcing is proven through purchasing decisions and evidence, not through possession of a policy document. The aim is neither impossible omniscience nor blanket supplier exclusion based on geography alone, but a disciplined system for locating where people are vulnerable and using whatever commercial influence exists to reduce that vulnerability, purchase by purchase. Procurement, on this view, becomes not merely a mechanism for acquiring goods and services at the best price, but a genuine instrument of responsible corporate conduct.
Human Rights and the Modern Supply Chain
Human rights within a supply chain cover the basic protections owed to
anyone producing goods or delivering services, regardless of nationality,
employment status or location: freedom from forced and child labour, protection
from discrimination, safe working conditions, reasonable hours and the right to
organise. Procurement becomes directly relevant wherever organisational spend
connects, however indirectly, with a person whose rights could be affected by
it.
A UK buyer may contract with a domestic Tier 1 supplier. At the same
time, production actually occurs through manufacturers, farms, mines and labour
agencies spread across several countries, each of which may itself subcontract
further. The legal distance between buyer and affected worker can therefore be
considerable, even though the demand the buyer creates is what ultimately funds
the economic activity employing that person, wherever they happen to be.
Global sourcing is not inherently exploitative — it has also driven
employment, investment and technology transfer across developing economies. The
risk arises specifically where economic opportunity meets weak governance,
poverty or a severe imbalance of bargaining power. Under those conditions,
workers can end up accepting terms that would be unlawful in the UK simply
because no realistic alternative employment or effective legal protection is
available to them.

Case Study: Cobalt Mining in the Democratic
Republic of Congo The Democratic Republic of
Congo (DRC) holds more than half the world’s cobalt reserves, a mineral
essential to batteries powering phones, laptops and electric vehicles. UNICEF
estimates around 40,000 children work in the country’s mines, some as young
as seven, earning roughly £1 to £1.50 a day for shifts of up to twelve hours.
Amnesty International traced cobalt mined partly by children into the supply
chains of major electronics and automotive brands. Because artisanal ore is frequently
blended with formally mined material before processing, buyers several tiers
downstream can purchase battery components with no practical visibility of
the mine of origin. |
Vulnerability is not spread evenly. Migrant workers, children, agency
labour and people working in the informal economy face disproportionate
exposure. Migrant workers are especially at risk where recruitment involves
substantial fees, employer-controlled accommodation or confiscated identity
documents — arrangements that can turn nominally voluntary employment into
circumstances a worker is financially or physically unable to leave, regardless
of what their contract says on paper.
Forced labour
rarely looks like a locked door. Coercion more often arrives through threats,
withheld wages, engineered recruitment debt or the threat of reporting an
undocumented worker to immigration authorities. This makes identification
genuinely difficult, because affected workers can appear, on a conventional
site visit, to be working entirely voluntarily. Procurement teams need to
understand these indicators of coercion rather than expecting victims to
identify themselves during a scheduled audit.
Child labour
requires similar precision. Not every job undertaken by a young person is
prohibited; international standards distinguish appropriate light work from
activities that damage health, safety or education. The greatest concern
surrounds children in hazardous work, excessive hours or informal, home-based
production — settings in agriculture, artisanal mining and small workshops
where conventional factory audits are structurally unlikely ever to reach.
The sector
shapes the specific risk. Labour-intensive manufacturing sees excessive
overtime and wage violations; agriculture relies heavily on seasonal or
informally recruited migrant labour; construction involves complex,
multi-layered subcontracting; mining can bring dangerous conditions and
community displacement. Logistics, cleaning, security and social care — sectors
operating far closer to home than a distant factory — can present comparable
risks that UK buyers sometimes overlook precisely because the supplier feels
familiar.
Production can
move from a regulated, auditable factory into small workshops or private homes
largely invisible to conventional supplier management. Subcontracting
frequently happens without the buyer’s knowledge, and sometimes without the
knowledge of the Tier 1 supplier itself. Where this fragmentation occurs, a
scheduled factory audit may faithfully examine the authorised workplace while
missing entirely the informal production happening around the corner from it.
Sudden
commercial pressure — a spike in demand, a compressed delivery schedule, an
unexpected shortfall — can push an otherwise responsible supplier towards
temporary labour or unauthorised subcontractors almost overnight. A supplier
assessed as low-risk at the point of contract award can look very different a
year later if it comes under sustained financial strain. Human rights due
diligence therefore cannot be treated as a one-off exercise completed during
tendering and then filed away.
Buyers can
respond to identified harm through contractual requirements, corrective action
plans, supplier development, commercial incentives, collaborative industry
initiatives or, ultimately, suspension. The right response depends on the
severity of the harm, the buyer’s actual relationship to it, and whether the
supplier shows genuine willingness to improve. Serious concerns demand
escalation, but disengagement should rarely be the automatic first move when a
workable alternative exists.
An organisation
may directly cause harm through its own practices, contribute to it through
purchasing behaviour that creates unreasonable production pressure, or be
linked to it through materials sourced from an abusive supplier several tiers
back. These are meaningfully different levels of responsibility. Recognising
which applies in a given case lets a procurement team calibrate a response that
actually matches its real relationship to the harm, rather than defaulting to
the same reaction regardless of cause.
Procurement teams are not being asked to solve every social problem in the global economy single-handedly. They are being asked to ensure that significant, foreseeable human rights risks connected with organisational spend are recognised, investigated and managed in proportion to their severity — treating human rights as part of ordinary supply chain governance rather than as a separate compliance exercise disconnected from everyday purchasing decisions.
Where Does Procurement Responsibility Begin and End?
Procurement
responsibility starts with decisions an organisation genuinely controls: what
is specified, which suppliers compete, how tenders are evaluated and what
obligations survive into the contract. These decisions shape working conditions
throughout a supply chain. Where procurement knowingly prioritises price or
speed while disregarding a credible human rights warning, that responsibility
cannot be discharged simply by inserting a clause and moving the risk onto the
supplier’s paperwork.
The clearest
responsibility sits within direct contractual relationships. Tier 1 suppliers
can reasonably be held to selection criteria, contractual obligations, audit
rights and performance management, and can be required to prohibit forced and
child labour outright. Confining scrutiny to Tier 1 alone, however, leaves an
obvious gap: much of the actual manufacturing, growing, extraction or labour
supply happens through subcontractors operating well beyond that first, visible
layer.
Responsibility
extends beyond the contractual boundary, though its character changes with
distance. A UK buyer may have no direct agreement with a Tier 3 factory or
mine, yet its purchasing activity still connects to that operation’s economic
existence. Ethical procurement increasingly requires investigating material
risk in these deeper tiers, rather than treating the absence of a signed
contract as sufficient reason to leave a credible, serious concern
uninvestigated.
This does not
mean every purchasing organisation must identify every business in every chain
feeding it. A single manufactured product can contain components sourced
through hundreds of international relationships; pursuing universal
traceability regardless of risk would consume resources for limited protective
return. Responsibility is therefore necessarily targeted — concentrated on the
categories, countries and employment models where credible indicators suggest
serious harm is genuinely more likely.
Severity, not
just probability, should drive how far an investigation extends. A
low-probability risk can still justify substantial scrutiny where the potential
outcome is forced labour or dangerous child labour. Standard commercial risk
assessments tend to weight likelihood heavily because they were built for
financial exposure; human rights due diligence instead has to weigh the
seriousness and potential irreversibility of harm to a real person more heavily
than the statistical odds of it occurring.
Knowledge
changes the standard an organisation is held to. Credible information — from an
audit, a whistleblower, a worker complaint, an NGO report or unusual supplier
behaviour — creates a stronger obligation to investigate than existed
beforehand. Once that evidence exists, continuing to purchase without
reasonable follow-up becomes difficult to square with any meaningful commitment
to ethical sourcing, whatever the supplier’s original risk rating said at the
point of contract award.
The useful
distinction is between what an organisation actually knows, what it reasonably
should know given proportionate due diligence, and what genuinely could not
have been discovered. This keeps responsibility bounded rather than unlimited,
while denying deliberately weak visibility systems any credit as a defence. A
buyer that never looks cannot claim ignorance as a shield if competent supply
chain management would plainly have surfaced the risk.
Commercial
leverage sets a further practical limit. A multinational representing a large
share of a supplier’s turnover can demand real change; a smaller buyer
purchasing standard goods through an intermediary may have little direct
influence at all. Limited leverage does not eliminate responsibility, but it
changes the available response — smaller buyers can pool influence through
industry bodies, certification schemes or collective purchasing initiatives
where individual weight is insufficient on its own.
Responsibility
also extends to the buyer’s own purchasing conduct. Ethical requirements ring
hollow when a buyer simultaneously demands unrealistic prices, compressed lead
times or unpredictable order volumes that create severe financial pressure on a
supplier. These practices routinely encourage excessive overtime, informal
labour and unauthorised subcontracting — meaning responsibility involves an
honest look at whether the buyer’s own behaviour has helped create the very
conditions it says it wants eliminated.
Contract award
is not a finishing line. Ownership changes, production relocates,
subcontractors are added, and economic conditions deteriorate over the life of
an agreement. A supply chain judged low-risk during tendering can look
materially different years later, so contract management needs periodic review,
updated risk assessment and targeted verification, with monitoring intensity
tracking genuine changes in circumstance rather than running on a fixed,
calendar-driven cycle.
Nor does
responsibility end the moment a breach is found. Immediate termination protects
the buyer’s reputation but does not automatically protect the workers involved
— it can simply remove their income, encourage concealment, or push the same
production towards a less scrupulous buyer elsewhere. Where it is safe to do
so, procurement should weigh whether remediation and continued, closer
oversight could achieve a better outcome for the people actually affected than
a clean commercial exit.
There remain
circumstances where continued engagement is indefensible. Deliberate forced
labour, systematic exploitation, falsified evidence or persistent refusal to
implement agreed corrective measures show that remediation cannot realistically
succeed. Procurement must then be prepared to suspend orders or terminate
outright, in line with contractual rights and legal obligations — ethical
sourcing carries little weight if commercial dependency is allowed to override
action once serious, substantiated violations are confirmed.
Responsibility
therefore has no single, fixed contractual endpoint. It expands or contracts
with the severity and likelihood of harm, the organisation’s actual knowledge,
its contribution to the problem and the influence it can realistically
exercise. Procurement cannot guarantee ethical conduct at every tier of a
global chain, but it can identify where the significant risks sit, investigate
credible concerns properly, and show that purchasing decisions respond when
evidence indicates people are being seriously exploited.
The workable boundary is reasonable, demonstrable due diligence rather than unlimited liability for everything happening upstream. Procurement should be able to explain why particular risks were prioritised, what evidence was sought, how it was verified, what influence was exercised and why a given course of action was chosen. Where these decisions are systematic and documented, ethical responsibility becomes a practical governance discipline rather than an impossible promise of total control.
The Scale of Forced Labour and Child Labour
Forced and
child labour persist across agriculture, manufacturing, mining, construction
and domestic work despite decades of prohibition and corporate commitment. The
scale is why ethical sourcing cannot be treated as a marginal corporate
responsibility exercise: 17.3 million of the 27.6 million people in forced
labour worldwide are exploited within the ordinary private economy, not in
isolated criminal enterprises operating outside legitimate commerce entirely —
meaning the exploitation genuinely can, and does, connect with mainstream
international supply chains.
Coercion, in International
Labour Organisation (ILO) methodology, covers far more than workers held under lock and key. It
reaches state-imposed forced labour, affecting 3.9 million people, and forced
commercial sexual exploitation, affecting 6.3 million, alongside the 17.3
million in the wider private economy. Almost one in eight of all people in
forced labour is a child, and more than half of those children are in
commercial sexual exploitation — the single starkest illustration of why this
scale cannot be dismissed as a marginal, developing-world problem.

Case Study: Child Labour in West African Cocoa Côte d’Ivoire and Ghana supply
around 60 per cent of the world’s cocoa, much of it destined for UK chocolate
brands. A 2020 National Opinion Research Centre (NORC) study, commissioned by
the US Department of Labour, found 1.56 million children working in
cocoa-growing households across the two countries, with 1.48 million exposed
to hazardous tasks such as land-clearing with machetes, agrochemical handling
and night working. Cocoa is typically aggregated from thousands of
smallholders before reaching a processor, meaning a UK confectionery buyer’s
contractual supplier may be four or five tiers removed from the farms where
the children were found. |
The financial scale is equally stark. ILO research published in 2024
put annual illegal profits from forced labour at approximately US$236 billion,
roughly £175 billion, up by around US$64 billion since 2014. Profits are
highest in Europe and Central Asia at US$84 billion a year, ahead of
Asia-Pacific at US$62 billion — a reminder that forced labour profits are not
confined to the world’s poorest regions but run directly through wealthy,
developed economies as well.
Forced labour is not simply physical confinement. International
estimates capture withheld wages, deceptive recruitment, debt bondage,
restricted movement and abuse of vulnerability, alongside more overt coercion.
Migrant workers face heightened exposure wherever employment depends on a
recruiter, a visa sponsor or employer-controlled accommodation. Procurement
teams looking only for dramatic evidence of physical coercion risk missing the
quieter, far more common mechanisms through which a worker effectively loses
the freedom to walk away from a job.
Children represent a substantial share of this vulnerability. The ILO
and UNICEF’s 2025 estimates found nearly 138 million children in child labour
during 2024, including around 54 million in hazardous work likely to damage
their health or development. That figure has fallen by over 20 million since
2020, a genuine improvement, though still far short of the international
commitment to eliminate child labour, and progress would need to run roughly
eleven times faster to hit a 2030 target.
Agriculture accounts for the largest single share of global child
labour, covering farming, livestock, forestry and fishing. This matters
enormously for procurement because agricultural commodities routinely pass
through several intermediaries before reaching a manufacturer, retailer or UK
supermarket shelf. Cocoa, coffee and cotton are frequently aggregated from
thousands of small producers, which makes farm-level conditions genuinely
difficult to establish from information supplied by the immediate contractual
supplier several steps downstream.
Once raw materials are aggregated, refined or processed, tracing their
origin becomes considerably harder. Artisanal and small-scale mining
illustrates the problem starkly: minerals extracted through informal, often
hazardous operations can enter formal trading networks and emerge as apparently
legitimate inputs, allowing a sophisticated manufacturer at the end of a long
chain to purchase materials whose earliest production stage would clearly
breach its own published ethical standards, entirely unknowingly.
Geography matters but should not become a shortcut. Human rights risk
is generally highest where poverty, conflict and weak institutions intersect,
yet forced labour is not confined to developing economies. It occurs within
wealthy economies too, through informal employment, criminal networks and
vulnerable migrant workforces — meaning an ethical sourcing system built solely
around a list of high-risk countries can miss significant exploitation
occurring much closer to the buying organisation’s own operations.
The United Kingdom is not insulated. Home Office figures show 19,125
potential victims of modern slavery were referred into the National Referral
Mechanism in 2024, a 13 per cent rise on the previous year and the highest
annual total since the mechanism began in 2009. The Global Slavery Index
separately estimates as many as 122,000 people may be living in modern slavery
in the UK at any one time — a figure the NRM’s own referral count captures only
a fraction of.
These statistics require careful reading, because forced and child
labour are inherently difficult to measure. Victims may fear employers,
recruiters or immigration authorities and consequently avoid reporting their
circumstances; informal workplaces sit outside regulatory systems altogether,
and illegal subcontracting can be deliberately structured to conceal itself.
Official estimates therefore represent a sophisticated attempt to measure
something largely hidden, meaning the true scale facing procurement is
plausibly greater than the headline figures alone suggest.
Nor does operating in a higher-risk country or sector automatically
make a given supplier unethical. That assumption produces crude decision-making
and can penalise responsible businesses that provide valuable, legitimate
employment within otherwise vulnerable communities. Geographic and sector risk
indicators should trigger proportionate investigation, not a blanket
presumption of guilt — they identify where greater scrutiny is justified, not
evidence that any particular named supplier has actually broken the law.
No single procurement organisation can eliminate forced or child
labour globally, given that the underlying drivers include poverty, weak
governance and conflict well beyond any buyer’s control. Aggregate purchasing
behaviour nevertheless creates real commercial incentives. When buyers
consistently demand traceability, responsible recruitment and verifiable
remediation, suppliers gain a genuine commercial reason to improve conditions throughout
their own sourcing networks, rather than treating human rights compliance as an
optional, easily-dropped extra.
The figures expose a persistent gap between formal prohibition and practical elimination. Forced labour is unlawful almost everywhere, and international commitment against child labour is decades old, yet well over 150 million people remain affected across the two categories combined. Procurement cannot assume legislation or supplier declarations have already closed that gap. The continuing scale of exploitation is precisely why ethical sourcing needs evidence reaching beyond corporate assurance and into the parts of a supply chain where vulnerable people actually work.
Beyond Good Intentions: Making Ethical Sourcing Measurable
Ethical sourcing ultimately stands or falls on whether commitments
translate into better conditions for the people who make products and deliver
services. Policies and supplier codes set expectations but cannot, by
themselves, demonstrate that anyone met them. Credible governance requires
organisations to identify where genuine risk sits, investigate proportionately
beyond the immediate contract, obtain meaningful evidence, and act when
practice on the ground diverges from what the organisation publicly claims to
require.
Visibility is the central practical difficulty. A modern supply chain
can span manufacturers, subcontractors, labour agencies, processors and
informal producers across multiple jurisdictions, and even a well-run Tier 1
supplier may have only partial knowledge of its own upstream network. Knowing
the contractual supplier is not the same as knowing the supply chain; genuine
transparency requires progressive mapping, concentrated where geography,
commodity and workforce characteristics point towards heightened exploitation
risk.
Visibility alone guarantees nothing. Knowing a factory or farm exists
says nothing about how its workers are actually treated. Verification requires
stronger evidence — worker testimony, employment records, recruitment
documentation, payroll data, independent assessment and targeted audit — with
the bar rising as potential severity rises. Forced labour and hazardous child
labour warrant substantially more rigorous verification than a comparatively
minor procedural gap in an otherwise compliant supplier’s paperwork.
A risk-based approach beats a universal one. Applying identical
scrutiny across every supplier and category generates administrative volume
while starving the highest-risk relationships of proper attention. Prioritising
by severity, likelihood, geography, sector and available leverage accepts that
perfect visibility is rarely achievable, and instead concentrates limited
investigative resource — auditor time, translation budget, unannounced site
visits — precisely where responsible intervention is likeliest to make a
measurable, real difference to actual working conditions.
The buyer’s own commercial behaviour has to form part of any honest
assessment. It is contradictory to demand fair wages and safe hours from a
factory while simultaneously imposing prices or delivery windows that make
lawful employment practically unviable. Commercial pressure cascades until the
weakest party in the chain absorbs the consequences — usually the worker with
the least power to refuse. Responsible sourcing therefore requires purchasing
practice and ethical expectation to actually align, not merely coexist on
separate pages of the same contract.
Supplier engagement matters as much as supplier policing. Procurement
should set clear expectations and require suppliers to extend equivalent
standards through their own networks, but relationships built purely on
compliance and punishment tend to encourage concealment rather than genuine
improvement. Where a problem is genuinely fixable, collaborative remediation,
capability building and continued verification frequently produce better
outcomes for workers than immediate disengagement — the objective should always
be protecting people, not protecting the buyer’s own reputation.
That principle matters most once a violation is actually discovered.
Termination can be necessary — particularly where exploitation is deliberate,
or evidence has been falsified — but withdrawal can also strip a workforce of
its income without correcting the underlying condition that created their
vulnerability in the first place. Decisions should weigh severity, supplier
cooperation, available leverage and the realistic consequences for affected
workers, without ever quietly subordinating a serious, substantiated concern to
short-term commercial convenience.
Measurement needs to move beyond activity counts. Recording how many
suppliers signed a code of conduct or completed a questionnaire demonstrates
administrative coverage, not worker safety. More meaningful indicators track
supply chain visibility, risks actually identified, corrective actions closed
out, remediation outcomes and repeat violations. Ethical sourcing performance
should ultimately be judged on whether an organisation’s intervention
measurably reduced real human rights risk, not on how much compliance paperwork
it generated along the way.
Governance matters because the hardest cases always involve competing
pressures. A serious ethical concern can surface involving a strategically
important supplier, a scarce commodity or a commercially valuable contract
precisely when walking away is most costly. Clear governance establishes who
can accept risk, who owns remediation, when senior leadership must be pulled
in, and what circumstances trigger suspension. Without that clarity, even
well-designed due diligence tends to fail exactly when the commercial stakes
are highest.
Procurement carries more influence than it often credits itself with.
Every specification, evaluation criterion, pricing decision and supplier review
signals what an organisation genuinely values, as distinct from what its policy
document states. When human rights expectations carry real commercial
consequences, suppliers have a strong incentive to investigate their own
networks. When those expectations evaporate the moment price or delivery
becomes inconvenient, the commitment was symbolic all along — and suppliers
generally learn that distinction faster than head office does.
The objective is not a flawless audit trail proving procedures were followed to the letter. It is measurably reducing the probability that spend contributes to exploitation — looking past Tier 1 assurance, questioning unexplained gaps, listening to workers directly, and recognising when a buyer’s own commercial practices are themselves generating risk. The strongest programmes combine transparency, evidence, leverage and remediation within ordinary contract management, rather than treating human rights as a separate exercise bolted on beside it.
Ethical sourcing is a continuing discipline, not a certificate earned once and filed away. Supply chains, subcontractors and labour markets keep changing, and new vulnerabilities emerge as they do. Organisations have to keep testing whether their understanding remains current and whether controls still function as intended. Moving from stated commitment to verified practice means replacing assumption with evidence — and accepting that responsible procurement begins wherever a purchasing decision has any real capacity to shape how a person, somewhere in that chain, is actually treated.
