Kaiser Permanente Colorado on Thursday fired back at the union representing thousands of its workers, saying the coalition has mischaracterized the company’s position during negotiations as workers move closer to striking next month.

The Service Employees International Union Local 105, which represents more than 3,500 Kaiser workers in Colorado, announced Wednesday that 96% of its voting members supported authorizing a nationwide strike over unfair labor practices.

In a statement Thursday, Kaiser Permanente Colorado derided the union for using “disruptive tactics,” saying it has misrepresented the company’s latest proposals.

“SEIU leadership seems more interested in a power play to position themselves vis-a-vis other Kaiser Permanente unions — rather than focusing on what is best for their membership,” the company said. “At a time when we are working hard to keep our care affordable, the Coalition’s demands are not fair to our members and the communities we serve.”

Kaiser added in the statement that “contrary to the union’s claims, there are no pay cuts and no changes to our employees’ pension benefits under our most recent proposal.”

The union in December charged Kaiser with failing to bargain in good faith since the national contract expired in September 2018.

“Since then, Kaiser has continued to commit unfair labor practices,” the SEIU Local 105 said Wednesday in a news release.

Contract talks fell apart in July, leading the union to hold a three-week vote over whether to authorize a nationwide strike. More than 80,000 Kaiser workers around the country weighed in.
