CO-OP CITY - The management company of Co-op City is refuting a contention by striking union members that a new contract doesn't include a pay raise.

RiverBay Corporation says it offered a 2.33-percent pay raise to Local 32BJ, which represents maintenance workers, porters and groundskeepers at the sprawling housing complex.

When Co-op City union workers last went on strike in the 1980s, it lasted for nearly a month.
