Approximately 190 Ambridge Area School District teachers are on strike.
Schools are closed Tuesday after educators in the Beaver County district walked off the job following months of contract negotiations. The school board and teachers' union remain at odds over salaries and health benefits.
Specifically, the district says the teachers pay only $25 per month for full family health care coverage, and are balking at a proposed increase in their share of the monthly premium.
The teachers' contract expired in June 2015.
The district says it anticipates the state Education Department will order teachers to return to work during the first week of January.
