PEO's work by assuming some of the employer risks and responsibilities for your employees. They lease those same employees back to your business while administering some or all of the employee benefits, human resource services, risk management, payroll, tax administration and workers' compensation insurance. Employees have access to benefits such as group health, 401(K) plans, cafeteria 125 plans, life and dental insurance options. Many PEO's offer even more value added benefits and services to help you and your employees succeed.
