Unite Here Local 26 is the union that represents the roughly 1,400 workers at Encore Boston Harbor. Housekeepers, cocktail waiters, chefs, dishwashers, and bellhops are among the casino employees who belong to the union. Table game dealers and slot attendants are not covered by the labor organization as they work in the gambling industry. Workers at the Wynn property say they deserve a bigger cut of the casino’s riches and they’re threatening to walk off the job unless casino management agrees to increase their compensation.
