What is a Co-Employment?

Co-employment is a legal relationship in which two or more organizations share employer rights and responsibilities over the same worker. It most commonly arises when a company uses workers supplied through a staffing agency, temp firm, or PEO: the agency serves as the worker's legal employer of record, while the client company directs their day-to-day work. Co-employment is not inherently illegal — the PEO industry is built on it — but when it goes unmanaged, it can expose the client to "joint employer" liability for things like wage-and-hour claims, benefits, discrimination, and wrongful termination, even for workers the client does not technically employ.

How Co-Employment Arises

Co-employment happens whenever employer responsibilities for one worker are split between two organizations. The most common scenarios are:

Staffing and temp agencies — the agency hires, pays, and formally employs the worker, but the client controls their schedule, tasks, and workspace
PEOs (Professional Employer Organizations) — the PEO and client intentionally share employment duties under a co-employment agreement
Long-tenured contractors — independent contractors or "temps" who work full-time hours, for long periods, under close day-to-day direction, until they start to look like employees in practice
Managed service providers — vendors whose staff become embedded in the client's teams and processes

The risk isn't the arrangement itself — it's the gap between how the worker is classified on paper and how the relationship actually functions. The more control a client exercises over a supplied worker, the more likely a court or agency is to treat that client as a joint employer.

The Risks of Co-Employment

When a client is deemed a joint employer, it can inherit employer obligations it never intended to take on:

Wage-and-hour liability — responsibility for minimum wage, overtime, and unpaid-wage claims under the FLSA
Benefits claims — long-term "temps" arguing they should have received employee benefits
Discrimination and harassment claims — exposure under Title VII and similar laws for workers on the client's premises
Collective bargaining obligations — potential duties under the NLRA if workers organize
Wrongful termination and misclassification claims — see worker misclassification for the tax and penalty exposure

The landmark example is Vizcaino v. Microsoft: long-term "permatemps" were ruled common-law employees entitled to benefits, resulting in a settlement of roughly $97 million. It remains the cautionary tale for treating supplied or contingent workers like employees without accepting the employer obligations that come with it.

How to Avoid Co-Employment Risk

Co-employment risk is manageable with clear boundaries and the right engagement model:

Define work by outcomes — use a clear statement of work that specifies deliverables rather than directing hours and methods
Don't treat contractors like employees — avoid giving them employee benefits, performance reviews, company equipment, or a permanent seat on the org chart
Place employment liability with a third party — engage workers through an Employer of Record (for employees) or an Agent of Record (for contractors) so a single, accountable entity holds the relationship
Classify correctly from the start — apply the relevant tests before work begins, and re-check as the engagement evolves
Watch tenure and control — the longer and more embedded a supplied worker becomes, the more the relationship should be formalized

Frequently Asked Questions

Is co-employment illegal?

No. Co-employment is a legitimate and common arrangement — the entire PEO and staffing-agency industry is built on it. The legal problem isn't sharing employment duties; it's unmanaged co-employment, where a client directs a worker like an employee without accepting the employer obligations that come with it. Managed correctly, co-employment is perfectly lawful.

What is the difference between co-employment and joint employment?

The terms are closely related and often used interchangeably. Co-employment usually describes an intentional, contractual sharing of employer duties (as with a PEO). Joint employment is the legal finding — often unintended — that two entities are both employers of a worker and therefore share liability. In short, co-employment is the arrangement; joint employment is the liability status a court or agency assigns.

Who is liable in a co-employment relationship?

Both parties can be. If a client is found to be a joint employer, it can share responsibility for wage-and-hour violations, discrimination claims, benefits, and more — even for workers formally employed by a staffing agency. That's why placing the employment relationship with a single accountable entity, such as an Employer of Record, is the cleanest way to control exposure.

Does using a staffing agency create co-employment?

It can. When an agency employs a worker but the client controls their day-to-day work, both may be treated as employers. The risk grows with longer tenure and tighter day-to-day control. Clear contracts, outcome-based scopes, and routing employment through an accountable third party all help keep the relationship from becoming a liability.

How can I avoid co-employment risk with contractors?

Classify each worker correctly before they start, define the work by deliverables in a statement of work, avoid treating contractors like employees, and engage them through an Agent of Record or Employer of Record that holds the legal relationship. WorkGenius handles all of this as part of its platform.
