ST. PAUL, Minn. (AP) - Documents reveal that at one point a union for faculty in the Minnesota State Colleges and Universities system asked trustees to fire Chancellor Steven Rosenstone.

Reports say leaders of the Inter Faculty Organization union wrote to trustees in November asking for Rosenstone's removal over his plan to overhaul MnSCU. The proposal was refused.

MnSCU board Chairman Tom Renier says trustees then saw a need to intervene more in the dispute.

The union president says it has "moved on" from the letter since relations improved with trustees, but Rosenstone hasn't participated in talks.

Rosenstone says the plan, called "Charting the Future," tries to make college cheaper and would see campuses coordinate more for programs and support services. But union leaders say it would result in a one-size-fits-all approach.
