Before MSU started construction on the Union, they held a referendum asking if students would be willing to pay for a Union Fee. It passed easily, however, getting it passed IHL was not that easy. However, it passed, and I believe that is $30.00 a semester for full-time students, which pays off the Union and goes to Union operations.
Several years back IHL ordered all fees and service charges be folded into tuition, instead of a stand along student activity fee. The fees now go to support the Sanderson Center, student tickets and other events, but the student activity fee was also what supported Music Makers and CAB, and when they got rolled into the tuition, those orginizations were no longer funded. That is when you saw a drop off in the number of concerts and big time bands coming to campus go down.
