Joint Employer Liability: Staffing, Franchising, and Shared Control

A business can be the employer of someone it never hired, does not pay, and has never had on its payroll system. That is what joint employment means: two entities are both treated as the employer of the same worker for a particular statute's purposes, and each carries that statute's obligations.

The mistake worth avoiding at the outset is treating it as a single question. There is no general definition of joint employer in federal law. The wage statute, the labor statute, the anti-discrimination statutes, the leave regulations, and the notice statute each supply their own, and they do not line up.

Five regimes, five questions

Read the table as five separate exercises. A general contractor may be a controlling employer for safety purposes with no wage liability at all. A franchisor may avoid bargaining obligations and still be named in a harassment suit brought by a franchisee's employee.

The three analyses that decide most disputes

The wage analysis

For minimum wage and overtime, the touchstone is economic reality. Circuits have articulated the factors differently — some using a four-factor control formulation focused on hiring and firing, supervision and control of schedules, rate and method of payment, and maintenance of employment records, others adding factors about the permanence of the relationship, the degree of skill required, the use of the putative employer's premises and equipment, and whether the work is integral to the business.

The regulatory picture has been unstable. The Department of Labor issued a joint-employer rule in 2020, portions of which were set aside by a federal court that year, and rescinded the rule in 2021. There is no current federal regulation defining joint employment under the wage statute, so courts apply their own circuit's test. Confirm the governing formulation before advising, using current Wage and Hour Division material and its fact sheets as a starting point rather than an answer.

Two operational consequences deserve emphasis. Liability is joint and several, so an employee owed overtime can recover the whole amount from either entity regardless of who ran the payroll. And hours are aggregated: a worker splitting a week between two joint employers may cross forty hours even though neither entity's own records show it. Each employer also carries its own recordkeeping duty under 29 U.S.C. § 211, a point developed in payroll records and wage-hour audits.

The labor analysis, and why it keeps moving

Under the labor statute, joint-employer status determines whether a company must bargain with a union representing another company's employees, whether it can be held responsible for unfair labor practices, and whether it can be picketed lawfully in a dispute it considers someone else's.

The standard has changed repeatedly. A 2015 Board decision broadened it to reach reserved and indirect control. A 2020 regulation narrowed it, requiring substantial direct and immediate control over essential terms and conditions of employment. A 2023 rule would have returned to a broader standard covering reserved and indirect control over an enumerated list of essential terms; a federal district court vacated that rule in March 2024, and the Board subsequently abandoned its appeal, leaving the 2020 regulation in place.

Verify before relying: As of mid-2026 the 2020 regulation remains the operative standard, but this area has changed with every shift in Board composition since 2015 and remains subject to further rulemaking and litigation. Confirm the current position directly with the National Labor Relations Board before making a structural decision that depends on it.

The practical drafting lesson survives every version of the standard. Reserved rights matter. A services agreement giving a client the right to approve wage rates, veto assignments, or require discipline is evidence of control even if the client never uses the right, and under some formulations it is sufficient on its own.

Discrimination, harassment, and coverage thresholds

Federal anti-discrimination statutes apply common-law agency principles, asking which entity had the right to control the means and manner of the work. Courts also use an integrated-enterprise analysis for related companies, examining interrelation of operations, common management, centralized control of labor relations, and common ownership. The Equal Employment Opportunity Commission has long taken the position that a staffing firm and its client can both be responsible for a contingent worker, with each liable for discriminatory conduct it participated in or failed to correct.

Coverage thresholds make this more than an allocation question. Where two entities are joint employers, employees may be counted together to reach the minimum employee count that triggers coverage — which can bring a small business inside a statute it assumed did not apply.

The four settings where it actually arises

• Staffing and temporary labor. The highest-frequency setting. The client typically supervises daily work, which supplies most of the control factors, while the agency runs payroll. Both can be liable for wage claims and for harassment the client's supervisors commit.
• Franchising. Brand standards, required systems, and mandated training are ordinary franchise controls. Exposure grows when the franchisor moves from brand consistency into personnel — supplying scheduling or timekeeping software that constrains hours, approving individual hiring, or directing discipline.
• Subcontracting and construction. Multi-employer worksites generate safety citation exposure on a separate theory entirely, and general contractors that direct crew composition and schedules invite the wage analysis as well.
• Professional employer organizations. These arrangements are explicitly co-employment. The allocation of duties is contractual, and the client generally retains the operational control that the tests examine, so a PEO relationship redistributes administration rather than eliminating status.
• Reductions in force. Where affiliated entities are treated as a single employer, headcounts aggregate and the notice obligation for a mass layoff can attach to a company that thought it was below the threshold — see the WARN Act and state mini-WARN laws.
• Contractor engagements that were misclassified to begin with. If a worker is reclassified as an employee, the question of whose employee immediately follows, which is why the two analyses are usually run together with worker misclassification audits and settlement options.

Controls that actually reduce exposure

Contractual language is necessary and insufficient. A clause reciting that the parties are not joint employers has no effect on a statutory analysis that looks at conduct. What contract terms can do is allocate the cost of a finding and constrain the conduct that produces one.

• Define the supplier's exclusive authority over hiring, discipline, termination, pay rates, and benefits, and remove client approval rights over those items.
• Direct work through the supplier's on-site lead rather than by client managers supervising individuals directly, where the operating model permits it.
• Require the supplier to maintain the timekeeping and payroll records the wage statute demands, with an audit right exercised through records rather than through worksite direction.
• Include indemnification for wage, tax, and employment claims, backed by insurance with the client named where the policy permits, and confirm the supplier can actually pay.
• Address arbitration coverage expressly, since a client seeking to enforce a supplier's arbitration agreement is a non-signatory — the problem discussed in arbitration agreements at work.
• Prohibit the client from issuing handbooks, performance reviews, or discipline to supplier personnel, and train client managers on the distinction.
• Set an escalation path so complaints by supplier personnel reach the supplier and are documented, without the client conducting the investigation as though it were the employer.

The last item is the hardest in practice. A client that receives a harassment complaint from a temporary worker cannot ignore it — failing to act is itself a basis for liability — but investigating it exactly as it would for its own employee supplies more evidence of control. The workable answer is a joint protocol agreed in advance, with the supplier leading and the client cooperating and taking the site-level protective steps it controls.

Questions the desk gets

Does a no-joint-employment clause protect us?

Not by itself. Every regime looks at the operating relationship rather than the label, and no clause can waive a statutory obligation owed to a worker who is not a party to the contract. The clause is still worth including because it evidences intent and anchors the indemnity, but the protective work is done by the conduct rules that sit next to it.

If the staffing agency shorted the workers on overtime, are we exposed even though we paid the agency in full?

Potentially yes. Where joint employment exists, liability for minimum wage and overtime is joint and several, and payment of an agency invoice is not a defense to the worker's claim. The client's recourse is the indemnity, which is only as good as the supplier's solvency. That asymmetry is the practical reason to verify a supplier's wage practices before signing rather than after a claim.

Can a franchisor set brand standards without becoming a joint employer?

Generally yes. Standards governing product, appearance, service protocols, hours of operation, and required training have not on their own established status under most formulations. Risk rises with personnel controls — approving individual hires, requiring specific discipline, setting wage rates, or deploying systems that dictate staffing levels. Some states have enacted statutes addressing franchisor status directly, so check state law as well.

We use a PEO. Does that transfer the risk?

It transfers administration and can transfer certain tax obligations under specific programs, but it does not eliminate status. The client normally retains day-to-day supervision, which is where most of the control factors live. Read the service agreement to see which party bears wage, benefit, and discrimination liability, and confirm what happens if the PEO fails to remit withheld amounts.

Does joint employer status apply to leave and benefits too?

It can. The leave regulations expressly contemplate joint employment in staffing arrangements and allocate duties between primary and secondary employers, including who must restore the employee to a position. Benefit-plan eligibility is separate again and follows the plan's own definitions — the drafting issue covered in ERISA plan compliance basics.

Where the risk actually sits

Not in the contract file. It sits in the operating detail: the client manager who approves timecards, the scheduling system that assigns supplier personnel to shifts, the site lead who sends someone home for the day, the performance conversation held by the wrong person. Those facts are what an agency or a plaintiff's counsel will find, and they are created by people who have never read the services agreement.

Run the review in that order. Map who actually makes each decision about supplier or franchisee personnel — hiring, scheduling, discipline, pay, termination — and compare that map to what the contract says. Close the gaps in practice first and in drafting second. Then confirm the current standards, which continue to move, through the National Labor Relations Board, the Wage and Hour Division, and the EEOC.
