The Maine State Employees Association, MSEA-SEIU represents
the adjunct faculty for the University of Southern Maine.
That union also represents the faculty at the maritime college in Maine. Public college and universities are represented by several different unions. As I recall the Teamsters even organized one college faculty some years ago.
