EAGLEVILLE, Pa. — A school district near Philadelphia says classes will be canceled for a second day Tuesday amid a strike by teachers following the breakdown of contract negotiations.

Teachers in the Methacton School District in Montgomery County walked off the job Monday after failing to reach an agreement with the district Sunday night. The contract covering about 400 teachers expired at the end of June.

Union representatives say the school board wants teachers to pay a greater share of health care premiums. They said they could not accept the proposal without a corresponding increase in salaries.

The school board president tells Philly.com progress was being made and he hopes negotiations will resume quickly.
