Six former student affairs officials are suing the University of Southern Maine, charging that they lost employment there because of age bias, The Portland Press Herald reported. The university recently reorganized many student services functions, and many jobs were shifted, with those in old jobs allowed to re-apply for the new positions. Those suing, all over 50, say that their age was a factor in their not being hired. The university denies any discrimination. An unusual factor in the suit: One of the plaintiffs is a state senator. who formerly was director of career services and professional life development.
