The Beverly Hilton Hotel has negotiated a new labor contract with the main union representing its 430 employees that calls for a 20 percent wage increase over three years for housekeepers and smaller increases for other employees.

The agreement, to be announced at a press conference Thursday morning, would add $2.30 to the wages of all non-tipped Beverly Hilton employees and $1.25 to all tipped workers such as servers and porters. It also calls for hotel management to maintain the current health plan for employees while a restructured plan is negotiated.

The pact also sets up a program to increase the hiring of black workers and another program to evaluate the workload of housekeepers.

The agreement must still be ratified by the rank and file employees. The previous labor contract at the Hilton expired in June; since then, negotiations had continued with little or none of the public protests that have emerged at other L.A.-area hotels where unions are seeking to organize workers.

The Beverly Hilton recently completed an $80 million renovation. Hotel owner Benny Alagem also has proposed building two condominium towers and a related building on land next to the hotel. The city of Beverly Hills is evaluating the proposal.
