Co-op City building workers are moving toward a strike.
Hundreds of union members voted to authorize the action Thursday as they prepare for contract negotiations.
The union, 32BJ SEIU, represents 500 maintenance and grounds workers, garage attendants, porters, public safety dispatchers and garbage collectors who work at the Bronx complex.
They are negotiating with RiverBay Corporation, which runs the complex.
The workers' contract expires June 8.
They say they want a fair wage increase to keep up with the cost of living and maintain affordable health care.
Union officials note that 30,000 apartment building workers across the city recently ratified a similar contract.
The next bargaining session will take place next week.
