The latest canceled school day comes after a parent of three students went to court to ask a judge to order the striking teachers back into the classroom.
The strike is the longest teacher work stoppage in the state since the 1990s and follows nearly a half dozen others across Massachusetts in the last 20 months.
A handful of parents tried to get access to a closed news conference held by the teachers' union, while a mother of three is taking legal action in an effort to end the strike.
"A strike isn’t something unions enter into casually. They take such actions only when negotiations truly break down," writes one reader. Another writes that unions say "it’s all about the students and their needs except it’s not."
