Boston School Bus Drivers Begin Strike

City officials calling the move "illegal"

(Reuters) - Boston school students woke up on Tuesday to learn that most city school buses were not running due to what city officials described as an "illegal" strike by bus drivers who transport about 33,000 students each day.

The United Steelworkers of America Local 8751, which represents about 700 school bus drivers, had walked off the job, the Boston Public Schools system said in a statement posted on its website.
