Kaiser Permanente Hawaii and the union representing health-care workers resumed bargaining Wednesday for the first time in four months, but didn’t settle on a new contract.

Unite Here Local 5, representing 1,900 Kaiser employees who have been working without a contract for more than two years, said it didn’t make much headway in late-night negotiations.

The union organized a six-day strike earlier this month following objections to what it calls low proposed wage increases and a proposal to eliminate guaranteed pensions for new employees, a sticking point in the collective bargaining.

“It does not seem as if Kaiser, leading up to even tonight, was serious about coming to the table with a serious intent in terms of addressing some of these concerns around workload and patient care and of course the pension proposal,” said Local 5 spokesman Cade Watanabe. 

He said the union, however, is looking at additional dates to return to the bargaining table. The last time the company and union met for negotiations was in October. Kaiser representatives didn’t return calls for comment.

The union said Kaiser’s last offer included proposed wage increases of 4 percent over three years. That compares with a 14 percent pay raise for about 18,000 Kaiser nurses in California who went on a two-day strike in November.

The Kaiser employees include licensed practical nurses, medical assistants and housekeepers.

Local 5 has protested understaffing after Kaiser shut down its urgent care department at the Honolulu Clinic in March 2013 and laid off some workers. The union said it has lost 121 Kaiser workers since 2012 due to staffing cuts.

During the strike from Feb. 2 to Feb. 7, Kaiser blamed workers picketing in front of its medical facilities for delaying patient care by blocking drivers as they tried to get to their appointments, though the union has denied those allegations.

The state’s largest HMO closed 10 of its smaller clinics on Oahu and the neighbor islands during the strike and rescheduled elective procedures and nonurgent appointments while consolidating resources to its larger medical facilities.

This was the first statewide strike for Local 5 Kaiser members since 1986.
