Union Push Gains Steam Among Yale, Harvard Grad Students

Efforts to unionize graduate students at private universities are gaining momentum as the National Labor Relations Board shows new openness to arguments that they are not just students, but also school employees.

A union for teaching assistants is in place at only one private U.S. school, New York University, where the administration gave its blessing in 2013.

Since then, organizing campaigns have sprouted or gained new life at other major northeastern universities, including Yale, Harvard and Columbia. Students and schools around the country are closely watching the NLRB following its recent decision to reconsider its decade-old ruling that graduate student at private schools are not entitled to collective bargaining.

At Yale, the Graduate Employee and Students Organization delivered a petition to the administration last month at the latest of several rallies since the NYU decision. Supporters in attendance included New Haven’s mayor and Connecticut’s attorney general and its two U.S. senators, all Democrats.
