This database contains PDF copies of the collective agreements for each Michigan district for teachers, bus drivers, assistants, office workers and other employees. Union contracts include not only salaries and social benefits, but also information on class sizes, staff evaluations, school calendars and more. The Mackinac Center for Public Policy is working to update this database in a timely manner. We invite school districts to support us by sending copies of new collective agreements or links to these agreements to email@example.com.
