Under the terms of the 1978 Court Order in AFL-CIO v. Marshall, compliance staffing levels ("benchmarks") necessary for a "fully effective" enforcement program were required for each State operating an approved State plan. In 1992, Michigan completed, in conjunction with OSHA, a reassessment of the levels initially established in 1980 and proposed revised benchmarks of 56 safety and 45 health compliance officers. After opportunity for public comment and service on the AFL-CIO, the Assistant Secretary approved these revised staffing requirements on April 20, 1995.

The plan covers all private-sector employers and employees, with several notable exceptions, as well as State and local government employers and employees, within the State.
