A union representative says seven faculty members at the University of Southern Maine have been told they will lose their jobs as the school tries to trim $5 million from next year’s budget. A university spokesman says the number of layoffs will be larger. Bob Caswell said Monday he cannot say how many employees will be affected because the notification process won’t be completed for weeks. The university has yet to make an internal or public announcement about the layoffs, but both academic and administrative jobs will be eliminated. He tells The Portland Press Herald, that university officials have identified $4.4 million in savings so far. The music department will be hit hard, with one layoff and three positions left vacant. USM has campuses in Portland, Gorham and Lewiston.
