BOISE -- A lawyer representing former University of Idaho employees says he expects to file a lawsuit against the school on Friday.

Four retirees filed a tort claim in December saying the university violated early retirement agreements signed in 1999 and 2002 when unauthorized changes were made to their insurance benefits.

Retirees contend the school went back on a deal not to make them pay for health insurance premiums.

Moscow attorney Ron Landeck says nearly 270 employees were affected by policy revisions made last year and the university has not responded to the allegations.

Landeck says retirees are suing to reinstate the benefits outlined in the original agreements.
