BREAKING — Thousands Of Union Protestors Disrupt Yale Graduation

Thousands of union activists have swarmed downtown New Haven to force Yale University to negotiate a contract that would bring its recently formed union to the bargaining table.

Led by Yale’s graduate student union Local 33 Unite Here, the crowd is compromised of a mish-mash of local unions, students from up and down the East Coast, and Yale retirees. The protest is occurring directly outside the Ivy’s 316th commencement ceremonies and is set to bleed well into the afternoon. City officials have blocked off four streets (Elm St., College St., High St. and Church St.) and formed a police barricade between graduating students and activists.

“This street closure — in addition to those previously announced — is to provide ample space for the safety of all those involved in this morning’s commencement exercises at Yale and related protests and demonstrations,” read a release obtained by the New Haven Register.

Currently on hunger strike until their terms are met, Local 33 has contended that Yale is delaying negotiations and expecting that Trump will name new members to the National Labor Relations Board (NLRB) that are sympathetic to the university.
