URBANA, Ohio (AP) -- Nearly 100 employees of International Fiber Corp. have returned to work at the company's southwest Ohio plant after a tentative contract agreement ended a lockout of almost four months.

Business agent Don Minton with Teamsters Local 957 told The Associated Press employees returned to the Urbana plant Thursday after being locked out since May 3. Minton says union members will vote Tuesday on the proposed agreement. He declined further comment.

The Springfield News-Sun reports that IFC human resources vice president, Kirsten Lenartowich (len-NART-uh-wich) said Wednesday that the lockout was lifted and the 94 employees would return to work. She did not immediately return messages Thursday.

The last collective-bargaining agreement expired in February.
