Overview
Hiring temporary employees can be an efficient way to meet short-term demand, control labor costs, and test potential long-term hires. That efficiency comes with trade-offs: temporary staff often arrive with limited knowledge of your workplace procedures, specific hazards, and company culture, which raises the chance of mistakes and injuries.
Both employers and staffing agencies can share responsibility for on-site safety, training, and compliance. Understanding who is responsible for what — and confirming appropriate insurance and training — helps reduce risk and avoid costly incidents or citations.
Key takeaways
- Employers are generally responsible for on-site safety but agencies often share duties for training and payroll-related coverage.
- Confirming agency screening, training, and insurance reduces liability exposure.
- Document training, maintain oversight, and require proof of coverage before work begins.
How it works
When you bring temporary workers onto your premises, you control the work environment, assign tasks, and supervise daily activities; that control creates legal and practical responsibilities for their safety. Agencies supply workers, handle payroll, and may provide some training or insurance depending on the placement agreement.
To understand how responsibilities are divided, review the staffing agreement carefully and ask for written confirmation about who provides workers' compensation, general liability, and any industry-specific training or certifications. For programs that combine multiple risk elements, see Temporary Staffing Program for an overview of typical arrangements and coverages.
What it may cover (and what it may not)
Workers' compensation usually covers job-related injuries regardless of whether the worker is a direct hire or supplied through an agency, but who pays and which policy applies can depend on state rules and the staffing contract. Employers should verify that all temporary workers are covered by an appropriate workers' compensation policy.
Some exposures, like company vehicles used by temp workers, may require special endorsements. If temp workers drive employer or non-owned vehicles as part of their duties, consider reviewing options such as Temporary Staffing Hired and Non-Owned Auto (HNOA) Insurance to address that risk.
Staffing agencies also face liability for screening and training. For a deeper look at agency responsibilities, risk sharing, and common insurance solutions, see Temporary Staffing Agencies: Risks, Worker Safety, and Insurance Coverage.
Common mistakes to avoid
- Assuming the agency fully handles safety training without written confirmation.
- Failing to obtain certificates of insurance or written assignment of workers' compensation responsibility.
- Skipping a site-specific orientation that explains hazards, emergency procedures, and required PPE.
- Not documenting supervision or corrective actions after an incident involving a temporary worker.
Questions to ask an agent
Before you sign an agreement, ask the staffing agency who is responsible for workers' compensation, and request current certificates of insurance for both liability and workers' comp.
Ask how the agency screens candidates, what job-specific training they provide, and whether they supply documentation that you can keep with your personnel files.
If you have exposures such as driving, heavy machinery, or chemical handling, confirm whether the agency or your company is expected to provide specialized training or equipment, and whether additional insurance is recommended; if you're unsure, talk to an agent who understands temporary staffing risks.
Next steps
Create a short onboarding checklist for temporary workers that includes site orientation, hazard identification, required personal protective equipment, emergency contacts, and task-specific instructions.
Request and keep copies of the staffing agreement and insurance certificates on file, and build a practice of confirming coverage before allowing any temp worker to start. Regularly review these processes with staffing partners to close gaps and reduce exposure.
Frequently Asked Questions
Who is responsible if a temporary worker is injured on my site?
Responsibility depends on the staffing agreement and state rules, but employers controlling the worksite typically have obligations for safety; staffing firms may also have responsibilities for training and payroll-related benefits.
Should I require a certificate of insurance from the staffing agency?
Yes. Require current certificates for workers' compensation and liability to confirm the agency carries appropriate coverage for their workers.
Do temporary workers get the same safety training as full-time employees?
They should receive site-specific orientation and job-specific training, but practices vary; document the training and verify expectations with the agency.
