Warehouse work is increasingly shaped by complex supply chains, where subcontracting, precarious employment and lone working create distinct risks for workers.
Rapid growth in e-commerce and just-in-time delivery has driven widespread outsourcing and short-term contracts, resulting in insecure jobs, low pay and limited social protection.
Subcontracting and fragmented employment relationships obscure responsibility for working conditions, making it harder to ensure consistent standards across sites. Workers engaged through agencies or informal arrangements face unstable hours, unpredictable income and reduced access to rights or grievance mechanisms.
Warehouse work is increasingly individualised, with roles involving lone working or highly monitored environments driven by algorithmic management. This reduces opportunities for support, increases pressure to meet targets and heighten safety and psychosocial risks.
Together these factors weaken job quality and transparency and create operational and reputational risks across global supply chains.
Sub-Contracting + precarious employment
Subcontracting is widespread in warehousing and logistics. Client companies frequently outsource warehouse operations to third-party logistics providers, who then subcontract further to labour agencies or service providers –obscuring accountability for working conditions and labour standards.
Workers employed through labour agencies or subcontractors face precarious employment arrangements: short-term and zero-hour contracts and informal employment relationships. These undermine job security, access to social security, insurance and legal protections. Workers receive lower pay, fewer safety protections and less training than directly employed staff performing the same work.
Precarious employment weakens workers’ ability to exercise fundamental labour rights, including freedom of association and collective bargaining. Workers fear retaliation or non-renewal of contracts if they raise safety concerns or attempt to organise, which produces unsafe workplaces and prevents workers from raising issues and reporting safety risks.
Subcontracting chains can also obscure responsibility for occupational safety and health. Warehouse operators claim that labour agencies are responsible for worker training, while labour agencies may argue that safety management is the warehouse operator’s responsibility – and the gap between them is where injuries happen.
Isolation and lone working
Many warehouse roles involve isolation or lone working, particularly on night shifts, maintenance tasks, security duties or work in remote storage areas.
Workers operating alone face increased safety risks because assistance may not be immediately available in the event of an accident or medical emergency, and because it is harder for them to report safety concerns or seek support.
In large distribution centres, workers are physically separated from colleagues by automated systems and the vastness of storage areas. That physical separation delays emergency response times if a worker is injured or becomes trapped by equipment.
Lone workers are more vulnerable to workplace violence, harassment and intimidation, and isolation itself carries psychological effects. Workers performing solitary tasks for extended periods experience stress, anxiety and reduced job satisfaction.
Safe work design should ensure that isolation and lone working are reduced through communication systems, supervision and emergency response procedures.
