SAN DIEGO (FOX 5/KUSI) -- Over 800 Hotel Del Coronado workers are set to hold a strike authorization vote Friday. This includes concierge, greeters, housekeepers, front desk agents, cooks, stewards, dishwashers, servers, bussers, bartenders, bellmen, engineers, phone operators, doormen and valet workers.  Unite Here Local 30, San Diego’s hospitality workers union, announced the upcoming vote and explained that the employees are asking for raises and better workloads. They say Hilton, which manages the Coronado hotel, has not responded to their requests to set negotiation dates. If the there's a 'yes' vote for a strike, it does not mean a strike will occur immediately. It means the union’s negotiating committee would then be authorized to call a strike at any time after the contract expires on Oct. 31. If the union votes to move forward with a strike, it would join over 700 other Hilton workers from the Hilton San Diego Bayfront, who have been on strike since Sept. 1.
