ROCHESTER, N.Y. — Management at the University of Rochester Medical Center and the union that represents its caregivers and patient service workers, 1199SEIU, are returning to the bargaining table on Thursday as a strike looms.

Thursday, they gave the university their mandatory 10-day notice of their intended strike. The strike is set for December 13 from 6 a.m. to 11 p.m. and will involve 1800 employees.

The two sides have been working to come to an agreement on a new contract. This comes more than a week after union members voted overwhelmingly to approve a one-day strike.
