Like a leasing situation, a temporary staffing service recruits and hires employees and assigns them to clients to support or supplement the client’s workforce in special work situations, such as employee absences, temporary skill shortages or seasonal workloads. These workers are traditionally only a small portion of the client’s workforce.

PEOs do not supply labor to worksites. They co-employ existing permanent workforces and provide services and benefits to both the worksite employer and the employees.
