Co-Employment Model
Co-employment is a contractual relationship in which both the PEO (ADP TotalSource) and client business share employment responsibilities. The PEO assumes many of the client’s business duties, including providing HR advice and guidance, benefits administration and payroll and employee tax assistance. The client business maintains the day-to-day supervision of its staff and all management responsibilities, including day-to-day operations.
Partnering with ADP TotalSource doesn’t mean you’ll lose control of your business. Instead, the co-employment model that defines a PEO is a corporate advantage. Whether you have an HR department or not, co-employment helps your business reduce its HR burden and focus more on strategy.
