School bus drivers took to picket lines in Marlboro Monday morning, after negotiators failed to agree on a contract through the weekend.

“The Marlborough Public Schools has been notified that bus drivers will not be reporting to work today,” the district posted on their website early Monday, identifying walking routes and contingency plans for students and staff.

The transportation company for the schools, North Reading Transportation, and Teamsters Local 170 union representing the drivers have reportedly been in negotiations since January.

Another school bus driver strike was narrowly avoided in two neighboring districts. In Framingham, negotiators for NRT and the union reached a deal Sunday evening, a feat the school superintendent said felt like “a miracle.”

In Westboro, no contract deal was reached, but drivers decided not to strike Monday as talks continue.

An NRT spokesperson said the Marlboro talks are “centered around part-time jobs that currently are paying $34.00 per hour.”

The union is seeking a 22% raise for restricted CDL drivers, 7D drivers and monitors, the company said in a statement late Sunday night, arguing they already raised CDL wages by 30.8% at the start of the year.

The district, which contains 4,700 students, released contingency plans in case of a strike for students over the weekend. Schools will have police and school staff out to assist students within walking distance from their school, a limited number of bus routes and transportation for all special education students, the district detailed.

During the strike, Marlboro Public Schools said, students who cannot make it to school will not be penalized for their absence.

District leadership also pushed against the strike decision in a release Thursday, saying the strike will “disproportionately impact” high needs students.

“More than half of our students rely on our schools to provide breakfast and lunch and many others receive mental health services,” the district statement said. “Every minute in school is critical.”
