Workers’ compensation for staffing employees assigned to multiple client locations rests on a clear foundation: the staffing agency is the employer of record, and its policy provides primary coverage. The dual-employer doctrine extends certain protections to client companies, but it also creates shared safety responsibilities. For staffing agencies, the operational key is accurate payroll apportionment across classifications that reflect the actual work performed at each site. For clients, the key is clear communication about hazards and any changes to assigned duties. When both parties understand their roles, multi-site placements can be managed without gaps in coverage or unexpected liability.
How Does Workers Compensation Work When Employees are Assigned to Multiple Client Locations
The staffing agency is generally considered the employer of record for workers’ compensation purposes, meaning its policy provides the primary coverage regardless of how many client locations an employee visits. This principle holds in most jurisdictions, from Oregon to Washington to California. The staffing agency’s insurer receives the claim, manages benefits, and pays compensation. However, this does not mean the client is off the hook entirely. Many states recognize that an employee can have two employers for workers’ compensation purposes—the staffing agency as the “general employer” and the client as the “special” or “dual” employer. This dual-employer doctrine protects clients from negligence lawsuits by injured temporary workers, but it also means clients share certain safety responsibilities.
How Classification Follows the Work, Not the Worker
The most practical challenge in multi-client assignments involves employee classification and payroll reporting. Workers’ compensation premiums are calculated based on the type of work performed. A worker classified as clerical in an office carries a much lower rate than someone operating a forklift in a warehouse.
When a staffing employee moves between client locations with different risk profiles, the staffing agency must apportion the worker’s payroll across the appropriate classifications for each placement period. For example, if an employee spends 60% of their time at a manufacturing facility and 40% at a clerical office, the payroll needs to reflect those distinct exposures. This is not optional—understating payroll in higher-risk classifications can result in significant additional premium at audit.
The Role of Client Supervision and Control
While the staffing agency maintains the workers’ comp policy, the client controls the day-to-day work environment. This creates a shared responsibility for safety. OSHA considers staffing agencies and host employers to be joint employers for workplace safety purposes. Both parties have obligations to protect temporary workers from hazards.
When an employee moves between multiple client sites, this shared responsibility becomes more complex. Each client must communicate site-specific hazards to the staffing agency before work begins. The staffing agency, in turn, has a duty to inquire about conditions at each assigned workplace and verify that clients are fulfilling their safety obligations. If a client changes an employee’s duties after placement—assigning them to operate new equipment, for instance—that change should be reported back to the staffing agency so coverage classifications can be updated if necessary.
What Happens When an Injury Occurs
When a multi-site employee is injured, the claim process follows a clear chain. The employee reports the injury to the staffing agency, which notifies its workers’ comp insurer. The insurer manages the claim and pays benefits regardless of which client location the injury occurred at. The client where the injury happened cooperates by providing accident reports and workplace details.
Because the staffing agency’s policy is primary, there is typically no need to determine which client “owns” the claim. The dual-employer doctrine generally shields both the staffing agency and the client from tort liability once workers’ compensation benefits are available. The injured worker receives medical care and wage replacement through the staffing agency’s coverage, and the client’s own workers’ comp policy is not triggered for that claim.

Conclusion
Frequently Asked Questions
Which workers' compensation policy covers an injury when an employee works at multiple client sites?
The staffing agency’s workers’ compensation policy provides the primary coverage. The staffing agency is the employer of record for workers’ compensation purposes, so its insurer handles the claim regardless of which client location the injury occurred at. The client where the injury happened cooperates by providing accident reports and workplace details, but the claim itself flows through the staffing agency’s policy.
Can a client company also be considered an employer for workers' compensation?
Yes. Many states recognize that an employee can have two employers for workers’ comp purposes. The staffing agency is the general employer, and the client where the employee works is often considered a special or dual employer. This dual-employer status typically protects both parties from negligence lawsuits by the injured worker, but it also means clients share certain safety responsibilities at their worksites.
How are workers' compensation premiums calculated for employees at different locations?
Payroll is apportioned based on the classification of work performed at each location. If an employee splits time between a warehouse and a clerical office, the staffing agency reports payroll under the appropriate classification for each period. Accurate record-keeping of placements and duties is essential for correct premium calculation. Understating payroll in higher-risk classifications can result in significant additional premium at audit.
Who is responsible for safety when an employee works at multiple client sites?
Both the staffing agency and each client share responsibility. OSHA treats them as joint employers. The client controls the worksite and must communicate hazards to the staffing agency before work begins, while the staffing agency has a duty to inquire about conditions at each assigned workplace and verify that clients are meeting safety obligations. If a client changes an employee’s duties after placement, that change should be reported back to the staffing agency so coverage classifications can be updated if necessary.
