PLEASANTON -- A three-year dispute between food service workers and management at Castlewood Country Club is over, the union representing the workers announced Thursday.

Although locked out workers returned to the job in October, members of Unite Here Local 2850 voted 44-1 to approve a new contract Feb. 13. It resolved an impasse that began in February 2010 over workers' health care contributions and included a two-year lockout.

On Aug. 17, an administrative law judge with the National Labor Relations Board found that Castlewood management had maintained an unlawful lockout of the 61 workers. The judge recommended the club reinstate all displaced employees as soon as possible as well as pay them back wages and benefits.

The new contract does not include back benefits and wages but has a signing bonus and a health care package with a substantially reduced cost, said union spokeswoman Sarah Norr. "The workers determined that was their priority," she said.

Under the deal, workers will pay $225 per month for family health care, decreasing to $150 per month in the third year of the contract. In negotiations, Castlewood had proposed a $956-per-month family health insurance payment for workers, Norr said.

With the contract resolved, the union has called off its boycott of Castlewood and is urging clients who canceled their events during the dispute to return.

Norr said 46 of the 61 locked out workers chose to return to their jobs.
