Gov. Phil Murphy heralded a new contract for 32,000 state workers Tuesday as "reasonable and responsible," but his administration wouldn't say how much the deal's raises, backpay and bonuses will cost taxpayers.

The four-year agreement was ratified by members of the Communications Workers of America, which announced the results of the vote Tuesday afternoon. It expires June 30, 2019.

A spokesman did not respond to requests for information on the cost of the contract. Murphy's administration did say Tuesday those expenses were already built into this year's state budget and the governor's proposed budget for the fiscal year beginning July 1.

Some provisions in the new contract include:

* A 2 percent raise retroactive to August 2017 and a second 2 percent raise effective this July 1.

* Workers who were eligible for step increases -- the pay raises employees become eligible for when they hit certain longevity milestones-- will receive them retroactively, as well. The Christie administration had frozen these increments during the contract dispute with the union.

* Workers already at the top of their pay scale and not eligible for step increases will receive $650 one-time bonuses.

* Workers who were employed during the period covered by this new contract but who retired before April 4 of this year will receive the $650 bonus, not retroactive step increases that would have boosted their pensions.

* Eligible employees will receive retroactive clothing allowances.

* The state won't deduct health care premiums, typically a percentage of employees' pay, from the retroactive pay hikes.

Union leadership called the contract "fair" and a "great day for New Jersey and the working men and women who dedicate their lives to making state government run."

But a Republican lawmaker, state Sen. Anthony Bucco, R-Morris, criticized the terms of the deal, saying: "This wasn't as much a contract negotiation as it was a pure giveaway."

"It's outrageous that Governor Murphy would give massive salary increases that could top 20 percent to union members without demanding anything in return for taxpayers, like concessions on expensive health benefits," Bucco said of Murphy, a Democrat.

The Associated Press reported that the current state budget signed by former Gov. Chris Christie, included $85.6 million for salary increases and other benefits for public workers across state government, including in the executive branch and the judiciary.

Murphy's proposed budget includes $64.3 million, but it is not clear how much of that will be covered by the new contract.
