BOSTON (AP) — A union representing 14,000 New England janitors has reached a tentative contract agreement that allows them to avoid a strike.

A spokeswoman for Local 615 of the Service Employees International Union said early Monday that the agreement followed a day of negotiations that went beyond the union’s midnight deadline.

Several hundred janitors attended a candlelight vigil Sunday at LoPresti Park in East Boston and participated in a procession to the Most Holy Redeemer Church.

Janitors have complained that employers offer them as few as 18 hours a week, which prevents them from getting health insurance.

The local represents janitors in Massachusetts, Rhode Island and New Hampshire in talks with the Maintenance Contractors of New England.
