Members of Service Employees International Union (SEIU), Local 715, will take a strike-authorization vote Thursday afternoon unless more progress is made with the university during negotiations Wednesday.
The two sides negotiated through "much of the long weekend," Zev Kvitky said today. He is president of the United Stanford Workers, which is part of SEIU.
"We would rather take a (contract) certification vote on Thursday than a strike vote," Kvitky said.
The two sides are negotiating over wages and benefits.
SEIU represents about 1,200 Stanford service, technical and maintenance workers.
"We've made steady progress so far in negotiations," Diane Peck, executive director of human resources at the university, said last Friday. "Stanford is firmly committed to continue bargaining in good faith, and we are optimistic that this negotiation process will ultimately produce a contract that is very good for our employees represented by SEIU 715 and the university."
SEIU held a one-day strike last December of its hospital and university workers, who are under separate labor contracts.
If there is a strike vote taken Thursday afternoon, it will be to authorize the negotiating committee to decide when to call a strike and whether it will be a one-day or longer strike, Kvitky said.
The union estimated that that more than 500 Stanford workers marched at the university last Wednesday to demand a fair contract.
