Teachers union vows to fight imposed evaluation system

The Boston Teachers Union threatened legal action against the School Department on Tuesday if it unilaterally implements a new teacher evaluation system that could quicken the dismissal of unsatisfactory teachers.

The union told the School Department in a letter that it was “dismayed” the department would impose the new system on Sept. 4 without the union’s consent and said it may pursue the matter with the state Department of Labor Relations.
