Final answer:
No, staffing firms are not strictly liable for clients' unfair labor practices violations under the NLRA. Joint employer liability depends on the specific circumstances of the case.
Step-by-step explanation:
No, staffing firms are not strictly liable when clients' unfair labor practices violate the National Labor Relations Act (NLRA).
Under the NLRA, the employer, not the staffing firm, is primarily responsible for unfair labor practices committed by clients. Staffing firms may be considered joint employers with the client, but the level of liability depends on the specific circumstances of the case.
To determine joint employer status, the National Labor Relations Board considers factors such as the extent of control over essential employment terms, the hiring and firing of employees, and the supervision of work performed. If the staffing firm and the client share substantial control over the terms and conditions of employment, they may be jointly liable for unfair labor practices.
