Mayor Bloomberg announced labor agreements with eight unions yesterday representing nearly 10,000 workers, bringing the grand total of city employees with whom he has forged new contracts to 128,000.

“We’ve got close to half the city employees settling on basically the same pattern,” Mr. Bloomberg told reporters in City Hall.

That pattern was set back in April when the administration reached an agreement with the city’s largest union, District Council 37, to set the bar for the city’s negotiations with other municipal workers.

That agreement, and the agreements forged yesterday, increase wages by some 6% over the next three years. Those raises are financed largely on the backs of new workers in the form of lower starting salaries and fewer benefits.

The latest pact includes probation officers and highway and sewer inspectors. They will receive a $1,000 lump sum payment in addition to a 3% salary increase. An additional 2% in pay increases will be funded entirely by union concessions. Newly hired probation officers, for example, will work 40 hours each week instead of 37 1 /2 hours.

New employees will also lose one paid holiday, and have their number of sick days reduced.

The mayor also announced salary increases for New York City managers and commissioners who are not represented by unions, a move that is certain to rankle officials from unions that have not forged a contract with the city. The teachers, police, and firefighters are still holding out for a better deal.

“What has happened is that the mayor beat up on a couple more small unions and they went for it,” said one union official who declined to be further identified. “I don’t think the police and teachers will hear footsteps because of what the traffic agents and sewer inspectors did.”

Mr. Bloomberg took a swipe at the police, firefighter, and teachers unions, saying they ought to come to the table to discuss an agreement instead of “grandstanding on the steps of City Hall.”

Of the unions that are holding out for a better deal, the police union is most vulnerable, union officials said.

Their labor agreement is in mediation and the Public Employment Relations Board is supposed to come up with a solution. The police have enough wiggle room in their work rules – from two-man cars to overtime – that they could negotiate themselves a good-sized raise without busting the city’s budget by cutting back on those areas.

The teachers offer a stickier problem because their contracts aren’t in mediation, so they can wait the mayor out or await the infusion of cash expected to come into the city as a result of a court decision that found the state was shortchanging the city in education funding.
