Yale University dining hall workers and students join their Harvard counterparts for a union demonstration in Harvard Square on Thursday night. The protest followed a meeting and discussion and a negotiation session between Unite Here Local 26 and the University.

Harvard dining hall workers, students and Unite HERE members from across New England marched through the Yard Thursday night holding signs and chanting “we want justice” and “union power.”

The march ended in the area outside of the Holyoke Center where the crowd sung a version of “The Battle Hymn of the Republic” with lyrics adapted for the union.

As the marchers traveled through the yard swinging colorful glow sticks, accompanied by a union-led band, they picked up a number of spectators and drew some students to watch from the sidelines.

Earlier that day, University officials met with members of Unite HERE Local 26—the union that represents Harvard dining hall workers—as part of their contract renegotiations.

Union leadership offered few details about the nature of the negotiations and the University declined to comment late Thursday night.

Members of the Yale dining hall workers’ chapter of Unite HERE also met with University officials in that meeting.

Following that meeting, the union members met with student supporters in First Parish Church before kicking off the rally.

At the church, the two school’s unions discussed the differences in their contracts.

Harvard and Yale workers said they want many of the elements contained in the Yale workers’ contracts to be included in the newest contract for the Harvard dining hall workers, including full-time employment, more job training opportunities for workers, and increased job security.

“In New Haven, we have a source of inspiration,” said Unite HERE Local 26 president Brian Lang, who called five Yale workers up to the stage.

The Yale workers proceeded to discuss the struggle they endured before obtaining their current contract, including 11 strikes. The speakers said their struggle was ultimately worth the pay-off.

“We stand here today with full-time employment. We stand here with no lay-off language—period. We stand here with 100 percent free medical,” said Robert “Bob” Proto, president of Unite HERE Local 35, which represents Yale dining hall workers. “There’s a standard of quality of jobs that Harvard needs to raise up to Yale’s.”

Lang said that the Yale workers made a presentation to Harvard officials during the negotiations earlier in the day Thursday and that the Yale workers presented some “very concrete solutions to the problems we’ve been facing.”

Harvard dining hall workers also spoke during the First Parish Church meeting, saying that they are fighting for a contract that benefits the entire University.

“We’re here tonight to make life better for everybody,” said Ed Childs, a chef in Adams House and a union official. “The problem is there are some people on the other side who do not want to make life better. But we intend to win because we intend to be united, workers, students, and faculty.”
