Harvard reaches tentative deal with striking dining workers

The school announced Tuesday that it agreed in principle to a five-year contract with Unite Here Local 26, the labor union representing Harvard's dining workers.

The union asked Harvard to increase salaries to a minimum of $35,000 a year, and it opposed the university's plan to raise health care costs.

Daily picket lines outside Harvard drew celebrity supporters including Democratic Sen. Elizabeth Warren, a former Harvard Law professor, and actor Ben Stiller, who was in town filming a movie.

During the strike, Harvard has closed some dining halls, reduced its offerings and recruited temporary workers to feed students.
