COI For Event Staffing
A Certificate of Insurance (COI) that doesn't list your organization as "Additionally Insured" provides zero liability protection. Per ISO CGL form CG 20 10, additional insured status must be explicitly endorsed — and per NCCI, the average workers' comp claim in temp staffing exceeds $41,000.
Key Risk Areas
A COI is proof, not a promise. It confirms active insurance coverage — but you need to verify dates, limits, and named insured. Workers' comp is the most important line. No workers' comp COI typically means workers are 1099 contractors. Request it before the contract is signed, not the morning of the event. Being named addit
Additional Insured Is Non-Negotiable
Without "Additionally Insured" endorsement on the COI, you have zero protection under their policy.
Verify Before Every Event
COIs expire. An expired certificate provides no coverage. Confirm dates match every time.
Workers' Comp Must Match State
Coverage must be active in the state where the event physically takes place — not the agency's home state.
Umbrella Coverage Matters
General liability alone may not cover large-scale events. Ask for umbrella/excess liability documentation.
ISO Commercial General Liability form CG 20 10 governs additional insured endorsements. Without this endorsement, the hiring organization has no rights under the staffing agency's policy.
Workers' compensation is mandatory in 49/50 states (TX is elective). Per NCCI, average temp staffing claim: $41K+. Operating without coverage is a criminal misdemeanor in most jurisdictions.
Under the "borrowed servant" doctrine, client companies using uninsured temp staff assume employer liability. Courts in CA, NY, IL, and FL have consistently applied this standard.
The IRMI (International Risk Management Institute) recommends verifying COIs within 30 days of any event. Expired COIs provide no coverage — and expiration dates must match the event date.
Frequently Asked Questions
Common questions about insurance & risk transfer risk.
What is a Certificate of Insurance for event staffing?
A COI is a one-page summary document issued by an insurance carrier or broker that confirms an active insurance policy exists, identifies coverage types and limits, and names the certificate holder. In event staffing, it confirms the agency carries workers' compensation, general liability, and employer's liability insurance.
Why can't a gig platform provide workers' comp on a COI?
Workers' compensation is an employer obligation — it only applies to W-2 employees. Gig platforms that classify workers as 1099 contractors are not employers, so they carry no workers' compensation policy. When a platform cannot produce a workers' comp COI, it signals the worker classification model in use.
When should I request a COI from my staffing provider?
Before workers arrive on-site — ideally at the contracting stage, not day-of. Request it as part of the vendor agreement process, verify effective dates cover your event, and confirm the named insured matches the entity you contracted with. Many venues require a COI on file before any third-party workers are permitted on premises.
What should I do if a staffing provider cannot provide a COI?
Treat it as a material gap. A provider that cannot produce a workers' compensation COI typically is not employing workers as W-2 employees, which means workers' comp coverage does not exist for your event. Request clear documentation before proceeding.
