'Economically, the companies have made some movement but we are millions of dollars apart,' Ted Pappageorge, Culinary Union Secretary-Treasurer told reporters on a call. The union said it has some agreements in place with the casinos. The Las Vegas unions, considered among the most powerful in the country, are demanding higher wages, stronger protections against new technology that may threaten jobs, a reduction in steep quotas for housekeepers and improved safety for workers. The strike would be the first for the unions since 1991 and mirrors activity in the entertainment and auto industries where employees are seeking better compensation and benefits to deal with the higher cost of living and a tight labor market, and comes as companies report record profits.
