Answer and explanation:
The staffing firm and the client are the employers of the workers because in operations they work as joint employers. Joint employers share control and supervision of the activities of employees of two or more business entities. Usually one of the parties is in charge of providing the workers with the benefits imposed by law -wages, retirement accounts, and health care- while the other party handles the monitoring of the workers' performance. Some organizations such as staffing agencies, subcontractors or franchise operators handle their labor force under this regime.
