Westchester?s biggest union reached a tentative deal on a contract with the county Tuesday after its workers spent 1,000 days on the job without one.

More than 500 Westchester County civil service employees took to the streets earlier Tuesday to demand a new contract.

The contract deal struck by the Civil Service Employees Association, which represents 4,000 employees of county government, will run for six years and be retroactive. CSEA members will also receive additional compensation for the time they worked since the last contract expired, in 2006.

Union members celebrated with a victory march, yet protest chants continued from some. CSEA President Jack McPhillips says the proposed contract meets the union?s three biggest demands of pay raises each year, no bonuses replacing pay raises and health coverage that doesn?t require employees pay in.

The two sides plan to put the deal in writing Wednesday morning. CSEA and the county won?t discuss the terms of the deal until it is approved by members.

Westchester?s Deputy County Executive Larry Schwartz calls the contract a win-win.
