SHALER, Pa. (AP) — Teachers in a western Pennsylvania school district say they are beginning a walkout today after the breakdown of contract talks with the district.
Union and Shaler Area School District officials met for about six hours with a state-appointed mediator but were unable to reach agreement.
The Allegheny County school district announced on its website that all classes in the district would be canceled Tuesday.
Melissa Ravas, president of the Shaler Area Education Association, said teachers were expecting a new offer Monday but didn't receive one.
She said teachers will keep picketing until a settlement is reached or they are ordered back to work by the state.
The nearly 400 teachers have been working under the provisions of a contract that expired in the summer of 2011.
