Washington Staffing Agencies: Workers’ Compensation Questions Before a New Assignment

A staffing agency places a worker with a new client. The job title says “warehouse assistant,” but the day-to-day work could involve packing, machinery, loading vehicles or office administration.

For a Washington workers’ compensation review, that difference deserves attention before the assignment begins. Do not substitute a broad job title for a description of the work actually performed. Washington L&I maintains a specific temporary-staffing classification process and directs agencies to its account managers for classification questions. [1]

Understand which organization has the reporting role

L&I states that a temporary staffing company is responsible for paying workers’ compensation premiums for workers it supplies. Its guidance also explains that a client can be responsible for unpaid premiums if the staffing company fails to pay. [1]

That is a reason for both sides to understand the arrangement—not a reason to invent a private agreement that ignores state obligations. A certificate or contract label is not a substitute for following L&I’s process.

Start the review by recording the staffing company’s legal name, the client’s legal name, the relevant worksite and who supervises the assignment.

Build a usable assignment description

Create a brief that answers what the person will do, where they will work, which equipment they will use and whether duties can change during the shift.

For example, distinguish office scheduling from physically moving goods. Record whether the worker will drive, use powered equipment, work off-site or perform a task different from the initial request. This is an original preparation checklist, not a substitute for L&I’s official classification instructions.

Ask the client to confirm the description. A staffing coordinator cannot identify changes that were never communicated.

Use L&I’s current classification process

The agency’s published guidance describes special temporary-staffing risk classes and a process for new client assignments. Check the current instructions and obtain a determination from the appropriate L&I contact rather than choosing a class because it appears cheaper. [1]

Do not treat an insurer’s national payroll-based illustration as a quotation for a Washington staffing assignment. Washington’s state-fund reporting and rating need to be considered on their own terms. [3]

Record the classification advice, the source and date, and the assignment information supplied. When the underlying facts change, return to the question rather than assuming the original answer remains suitable.

Set a clear process for changed duties

Consider this illustrative example: a client initially requests a receptionist, then asks that person to spend part of the week doing stockroom work. The agency should not rely on the original title without reviewing the revised assignment.

A practical process identifies who at the client reports the change, who at the staffing agency receives it, and who checks whether further L&I guidance is needed. Put that process in the assignment administration workflow so it does not depend on someone remembering at quarter-end.

This recommendation is about getting accurate information to the right people. It does not assume that every change produces a different class or a higher premium.

Keep records that explain the reporting

Organize assignment dates, duties, approved classification information and the time records required by the applicable reporting rules. Reconcile changes with the people preparing the reports.

The question to ask is: could another responsible employee understand how this assignment was reported from the records alone? A note that says “same as last client” is weaker than a record linked to this client and this work.

Use the insurance audit preparation guide for a broader document checklist, while following L&I’s actual Washington instructions for the state account.

Do not use a contractor label to bypass the review

Some staffing arrangements involve separately contracted specialists. Whether a person is an exempt independent contractor requires its own analysis. L&I makes clear that a 1099 or business registration alone does not answer the coverage question. [2]

Provide the complete facts to the appropriate professional. Do not advertise blanket exemption based on a signed agreement or describe all supplied workers as contractors to simplify administration.

Review contracts, safety and insurance together

Clarify who provides orientation, equipment-specific training and incident reporting at the worksite. Have qualified advisors address applicable safety and legal requirements. Insurance does not replace those responsibilities.

Separately, ask the broker to review any private liability or employers’ liability requirements in the client contract. Those should not be confused with the L&I reporting process.

For the next assignment, send NRG an inquiry with the operating states and a non-sensitive description of the duties. Ask what insurance assistance is available, and direct state-fund classification decisions to L&I through the appropriate process.
