The University of Wisconsin Colleges will lay off more than 80 employees in a cost-cutting move that will see the network of two-year schools consolidate administration of its 13 campuses into four regions of the state, officials announced Tuesday.The move is one result of a $5 million cut to the college system’s funding — its share of a $250 million reduction in support for the University of Wisconsin System in the state budget Gov. Scott Walker signed last week.
