How the 'Direct Control' Standard Defines Joint-Employer Liability

When a logistics company brings 50 temporary workers into its warehouse to handle a holiday surge, the facility manager faces a critical legal boundary. If the manager simply tells the staffing agency what needs to be accomplished, the logistics company remains a client. But if that same manager starts assigning specific shifts, dictating hourly wages, or directly disciplining individual temp workers, the legal firewall collapses.[8]

This boundary defines "joint-employer" status, one of the most consequential designations in American labor law. When two businesses are deemed joint employers, they share legal responsibility for the same group of workers. For the client company, this means being forced to the negotiating table if the workers unionize, facing liability for unfair labor practices, and becoming a lawful target for strikes and picketing.[1][8]

The framework governing this boundary is the National Labor Relations Board's (NLRB) "direct and immediate control" standard. Formally codified in early 2026 after a decade of regulatory whiplash and federal court battles, the standard provides a strict, business-friendly test for determining when a contractor, franchisor, or client company crosses the line into joint employment.[1][2][3]

The core mechanism of the rule is precise: a company is only a joint employer if it possesses and actually exercises "substantial direct and immediate control" over the workers. Merely having the theoretical ability to influence working conditions is no longer enough to trigger shared liability.[1][5]

To apply this test, the NLRB strictly defines the "essential terms and conditions of employment." There are exactly eight: wages, benefits, hours of work, hiring, discharge, discipline, supervision, and direction. A company must exert direct control over at least one of these specific areas to be classified as a joint employer.[3][5]

The distinction between direct and indirect control is the pivot point of the entire framework. For example, a client company that sets the overall operating hours of its manufacturing facility is exercising indirect control. However, if that company dictates the specific shift schedule for an individual temporary worker, it has crossed into direct control.[2][3]

Similarly, the standard eliminates the "reserved control" trap that previously ensnared many businesses. In older regulatory frameworks, simply having a clause in a vendor contract that gave a company the right to reject a worker was sufficient to establish liability. Under the current standard, unexercised authority is irrelevant; the company must actually use that power to be deemed an employer.[2][6]

When it comes to compensation, the boundaries are equally rigid. Entering into a "cost-plus" contract with a staffing agency—where the client pays a set fee that covers the agency's labor costs plus a markup—does not constitute direct control over wages. The client must actually determine the specific wage rate paid to the individual worker to trigger liability.[2]

Hiring and firing decisions follow the same logic. If a warehouse manager tells a staffing agency, "we need ten more people next week," or "remove this specific worker from our site," they are not exercising direct control over hiring or discharge. The staffing agency retains the ultimate authority to hire the worker or reassign them to a different client.[2][3]

Supervision and direction require careful navigation by on-site managers. Describing the overall project to be completed or setting quality standards does not create a joint-employer relationship. However, assigning specific, granular tasks to individual workers or directly supervising their moment-to-moment methods crosses the line.[2]

Even if a company does exercise direct control, the NLRB requires that control to be "substantial." The intervention must have a regular or continuous consequential effect on the worker's employment. Sporadic, isolated, or de minimis instructions—such as a manager occasionally correcting a temp worker's safety protocol—do not meet the threshold.[3]

This framework is particularly vital for the franchise industry. The franchise business model relies heavily on strict brand standards, requiring independent franchisees to use specific recipes, uniforms, and operational software. Because the NLRB classifies these requirements as indirect control, franchisors can enforce brand consistency without becoming joint employers of the cashiers and cooks.[3][4]

Staffing agencies and their corporate clients also rely on this bright-line separation. Companies can utilize temporary labor to scale operations quickly without the risk of being dragged into collective bargaining agreements, provided they maintain strict operational boundaries and leave human resources functions entirely to the agency.[8]

Labor organizations argue that the direct control standard creates an artificial "regulatory gap." From their perspective, the company that controls the economic realities of the contract effectively dictates the workplace environment. Unions contend that allowing the primary economic actor to avoid the bargaining table leaves workers negotiating with staffing agencies that have little actual power to improve conditions.[2][8]

Conversely, corporate counsel and business groups maintain that the standard provides necessary predictability. They argue that without a strict direct-control test, routine business-to-business contracts would become legally hazardous, forcing companies to either abandon outsourcing entirely or micromanage vendor employees to mitigate the risks they are already absorbing.[3][7]

It is crucial for businesses to recognize that the NLRB's standard applies specifically to labor relations and union organizing under the National Labor Relations Act. Wage-and-hour disputes under the Fair Labor Standards Act (FLSA) are governed by the Department of Labor, which uses a different, broader "economic realities" test that can sometimes find joint employment where the NLRB does not.[4]

For human resources and operations leaders, the mandate is clear. Companies must routinely audit their vendor agreements to ensure contractual language aligns with the direct control standard. More importantly, they must train front-line managers to respect the boundaries of indirect control, ensuring that daily operational practices do not accidentally convert a vendor relationship into a shared legal liability.[8]
