Culinary Workers Union Local 226 is pushing about a dozen of its employers to contribute more money to its health insurance fund to cover rising Obamacare costs.

Currently, employers pay 100% of the premiums. The union, which is in contract negotiations, wants to keep it that way. But the spike Obamacare-related expenses could make it tougher to convince employers to pony up more money. …

“The administration has made change after change to meet other groups’ needs,” said Yvanna Cancela, the local’s political director, noting the union would like to see the president keep his promise. “Our members want to keep their health plans.” …

The Local 226 fund provides health insurance for about 55,000 kitchen workers, housekeepers, bartenders, bellman, porters, laundry workers and others, as well as 70,000 dependents. Employers contribute $3.96 per worker per hour to cover health and pension benefits. Workers don’t pay a premium, but are responsible for about 10% of their out-of-pocket medical costs.
