On May 22 at Yale University, 1,000 people marched across campus on graduation day, demanding that the university negotiate with Unite Here, a union that organized eight units of graduate students/workers in eight departments. Yale has contested the NLRB election, arguing that the eight units prevent the majority of graduate assistants from organizing. Earlier in the month, during a hunger strike by Yale graduate assistants, 23 people were arrested for blocking traffic as they protested the university's refusal to negotiate during the NLRB appeal process.
