By 1985, there were approximately 275 staff leasing companies in the United States. Each state in the U.S. has differing regulations for workers’ compensation insurance and state unemployment insurance, so PEOs are typically regulated at the state level. In 2004, President George W. Bush signed into law the SUTA Dumping Protection Act of 2004, which requires that all 50 states enact anti-SUTA-dumping legislation by 2007. Most states have now done so; however, federal law does not prohibit companies from using a PEO to obtain more favorable SUTA rates.
staff leasing industry itself has also taken steps to address abuses. It formed its first trade association, the National Staff Leasing Association (NSLA), in 1985. The association changed its name to the National Association of Professional Employer Organizations (NAPEO) in 1994 to reflect the term in current usage. An independent accreditation body, Employer Services Assurance Corporation (ESAC), was formed in 1995. ESAC’s purpose is to verify PEO compliance with important ethical, financial, and operational standards and to provide financial assurance backing the performance of its accredited PEOs. Currently there are 30 ESAC-accredited PEO groups comprising 136 PEO entities. PEOs may also undergo a certification process conducted by the independent Certification Institute (CI) formed in 2002. This certification verifies that a PEO’s workers’ compensation (WC) program is meeting proven insurance industry risk management best practices to reduce work-related accidents and health exposures and control WC insurance losses.
