TREVORTON -- It's back to class for some students in Northumberland County.
Teachers in the Line Mountain School District are back on the job Monday.
They hit the picket lines on September 16th, a week after school started.
There is still no contract for the teachers, but Monday was the deadline for educators to be back in the classroom to get in the required 180 days of class.
Teachers in Northumberland County have been working without a contract since 2012.
