What is co-employment?
Co-employment is when two organizations share legal responsibility as employers of the same worker, most often a company and a staffing agency or employer of record. Each party holds part of the employer relationship.
When co-employment happens
It arises whenever a third party holds the formal employment relationship while the client directs the day-to-day work. Agency placements and EOR arrangements are the common cases. It is a normal, intended feature of those models, not a problem in itself.
The risks of co-employment
The risk is ambiguity. If it is unclear who owns tax, benefits, direction, and liability, the arrangement can be challenged.
Key takeaway: Co-employment goes wrong when the lines are blurry, not when it exists. Clear contracts and a clear system of record keep it clean.
How to manage co-employment risk
- Define the split. Put who owns what in writing: employment, tax, benefits, direction.
- Keep one system of record. Track the worker, the contract, and the responsible party in one place.
- Watch tenure and control. Long, tightly directed engagements draw more scrutiny.
- Use a compliant intermediary. An EOR or AOR that takes clear employer or engagement responsibility removes the ambiguity.
Best practice: Let a single provider hold the formal relationship and document it clearly. Worksome acts as EOR or AOR, so responsibility for each worker is defined, not shared by accident.
Frequently asked questions about co-employment
Is co-employment illegal? No. It is a normal part of using agencies and EOR providers. The risk is in managing it poorly, not in the arrangement itself.
What is a joint-employer claim? A claim that two organizations are both employers of a worker and therefore share employer obligations. Clear contracts and defined responsibility reduce the exposure.
How does an EOR affect co-employment? An EOR takes on the formal employment relationship, which clarifies who the employer is, as long as the split of responsibility is documented.
Keeping co-employment clean
Co-employment is only a problem when nobody can say who owns what. A clear system of record and a provider that takes defined responsibility keep the lines sharp. Worksome holds that relationship as EOR or AOR.
