What does an alternate employer endorsement actually do?
An alternate employer endorsement extends your workers compensation policy to protect a named client as if that client were the employer of the workers you send them. It names a specific client and a specific job location, and it costs little or nothing to issue.
The reason it matters is exclusive remedy. Workers compensation is normally an injured worker's only route against an employer, which blocks a personal injury lawsuit. Without the endorsement, your associate can collect comp benefits from you and then sue the client separately, and the client's insurer will look straight back at you.
The endorsement pulls the client under that same protection, so the claim stays inside the comp system. Most staffing clients now require it by name in the service agreement.
- Names one client and one location, so four client sites need four endorsements
- Must be issued before the placement starts, since it is not retroactive
- Adds little or no premium at most carriers, so there is no reason to resist it
Why do client contracts demanding waiver of subrogation and additional insured status raise my cost?
Every waiver of subrogation and additional insured requirement gives away a recovery right or adds a party your insurer must defend, and carriers charge for both. A blanket waiver on workers compensation commonly adds 2 to 5 percent to the premium for that client's payroll.
Subrogation is your insurer's right to recover from whoever actually caused the injury. When a client makes you waive it, your carrier pays the claim and can never pursue the client, even when the client's forklift operator caused the accident.
Additional insured status on your general liability does something similar. The client gets your policy defending them for claims arising out of your work, usually primary and non-contributory so their own coverage never contributes.
- Blanket waiver of subrogation on comp typically adds 2 to 5 percent to the assigned payroll premium
- Primary and non-contributory wording puts your policy first in every dispute
- Defense of additional insureds can erode your limit if defense sits inside it
- Indemnity clauses often reach further than any policy will actually cover
What is co-employment, and who gets named when something goes wrong?
Co-employment means you and your client are both treated as employers of the same worker, and it usually means both of you get named in the claim. You control hiring, payroll, and benefits; the client controls the work, the schedule, and the supervision.
Courts and agencies apply a joint employer analysis that turns on who directs the work day to day. Because the client controls supervision, the client shares exposure for wage and hour claims, discrimination and harassment claims, and safety citations.
That matters because co-employment liability is not a comp issue at all. Injury goes to comp. Everything else, including how a supervisor spoke to your associate and whether an assignment ended lawfully, lands on employment practices coverage.
Do I need employment practices liability if the client does the supervising?
Yes, and you need employment practices liability with third party coverage, because the most common staffing claim is your associate alleging harassment or discrimination by the client's staff. Standard policies cover claims by your employees against you and stop there.
Employment practices liability, usually shortened to EPLI, pays defense costs and settlements for wrongful termination, discrimination, harassment, and retaliation. In staffing, the person doing the alleged harassing is often not on your payroll, which is exactly what the base form was not written for.
Third party coverage extends the policy to claims involving non-employees. Typical staffing limits run $1 million to $3 million with retentions of $10,000 to $50,000, and defense costs usually sit inside the limit.
- Add third party liability so claims involving client supervisors are covered
- Confirm temporary and contract workers are inside the definition of employee
- Check whether wage and hour defense is included, even at a small sublimit
When does a placed worker need professional liability coverage?
You need professional liability whenever you place workers who give advice, exercise licensed judgment, or produce technical work product, because general liability only responds to bodily injury and property damage. A coding error or a flawed drawing causes financial harm, which general liability excludes.
Professional liability, also called errors and omissions, covers the economic loss a client suffers from a mistake in the work. It is claims made, meaning the policy that responds is the one in force when the claim is reported, so continuous coverage matters as much as the limit.
Two placement types create the most trouble. Medical placements need medical professional liability, since standard errors and omissions forms exclude bodily injury from patient care. Technology and engineering placements need wording broad enough to cover work performed under the client's direction.
- Common limits run $1 million per claim and $1 million to $3 million aggregate
- Keep the retroactive date at your original inception, never let it reset
- Buy an extended reporting period if you change carriers or exit a class
How much do classification codes and payroll audits really affect my comp bill?
Classification codes are the largest single driver of your workers compensation cost, and misapplied codes are the most common finding in a staffing payroll audit. The same associate can cost under $1 per $100 of payroll in a clerical code or well over $10 in a construction code.
Staffing is audited more aggressively than most industries because your payroll moves between codes constantly. Auditors want time records tying hours to actual duties at actual client sites, not one default code applied to everyone on an account.
Keep records that survive the audit. If an auditor reclassifies a year of payroll upward, the extra premium arrives long after you invoiced the client at your old markup.
- Code by actual duties performed, not by the client's overall business type
- Keep job orders and time records linked to the assignment, not just the client
- Review the audit worksheet line by line before you pay additional premium
- Build markup on the true loaded cost, including comp, taxes, and benefits
How do I keep certificates of insurance compliant across dozens of clients?
Treat certificate compliance as a standing process rather than a task you handle when a client asks, because a missing endorsement found after a loss is what turns a covered claim into an uncovered one.
Build a tracker listing each active client, the limits required, which endorsements they demand, and the certificate expiration date. Review it monthly rather than at renewal.
Remember that a certificate is only evidence and confers no coverage by itself. If a contract requires an alternate employer endorsement, that endorsement has to be issued and attached to your policy.
How does my job class mix drive what I pay?
Your premium is driven less by how many people you place than by what those people do, since comp rates vary more than twentyfold between the safest and riskiest classes. Moving 20 percent of payroll from clerical to light industrial costs you more than adding 20 percent more clerical headcount.
Model the mix before you chase a new vertical. Staffing firms that price every placement off one blended markup lose money on the heavy classes and lose bids on the light ones.
Your experience modification factor, the multiplier comparing your loss history to firms of similar size and class, compounds the effect. A single serious claim can move it for three years, and many clients now refuse to work with a firm whose factor is above 1.0.
- Price each class code separately instead of applying one blended markup
- Model the experience modification impact before entering a higher hazard vertical
- Return to work programs shorten claims and protect the modification factor
- Ask your broker for a mix analysis at least 90 days before renewal
