UCLA says its campus and facilities will remain open during a five-day strike planned in January by electricians, elevator mechanics and other workers to demand higher wages.
UCLA spokeswoman Rebecca Kendall said Friday the university and UCLA Health medical center are developing contingency plans for the Jan 6-10 strike.
On Thursday, the union representing some 600 skilled-trade workers at UCLA voted to strike, saying the action was motivated by UCLA's "bad faith bargaining and numerous violations of labor law."
Teamsters Local 2010 warned the strike will cause disruptions.
Kendall said UCLA has been bargaining in good faith with the union for a fair contract since August and disputes all suggestions of "numerous violations" of state labor law and unfair practices.
The workers' contract expired in 2013. The union is striking over the university's refusal to negotiate over back wages.
