Unionized employees at Heritage Credit Union in Slocan Park and Castlegar are poised to issue 72-hour strike notice after turning down the employer's final offer last month.
In a news release, United Steelworkers Local 1-405 president Doug Singer said since bargaining began in May, the biggest stumbling block has been changes to the pension plan in 2010.
He said it was "identified by the membership as the number one issue on the bargaining table from day one."
The union has called upon a provincial mediator to help the parties reach a deal, but the issues couldn't be resolved, Singer said.
He added their bargaining committee will meet with workers one more time before issuing strike notice.
The union represents 35 employees at Heritage Credit Union and HG Insurance who have been without a contract since May 31.
The credit union also has a branch in Greenwood that is not unionized.
General manager Lorne Myrha wasn't immediately available for comment.
