Teachers on the North Shore of Massachusetts are back on the picket line, and students are out of school for another day. Friday officially marks one week of striking in two school districts, and there’s no deal in sight.

Teacher strikes in Gloucester and Beverly reached their fourth day of missed school Thursday, while Marblehead teachers were out for a third school day, after days of bargaining and mediation so far have failed to produce a deal in any of the three districts.

Teachers in Beverly, Gloucester, and Marblehead continue their strike, leading to class cancellations and ongoing negotiations with the school committees.
