The governor's signature was the last step needed to ratify the three-year agreement, which gives approximately 95,000 SEIU Local 1000 members a 4.5 percent raise by 2015.
Earlier this week, SEIU announced that the contract had been approved by 90 percent of its voting members, meeting the requirement that union membership, in addition to the state Legislature, approve the contract.
"This agreement recognizes the important role state employees have played in helping stabilize California's financial outlook over the last few years, " said Pat McConahay, a spokesperson for the Department of Human Resources. "As a result of their contributions, they will receive modest pay increases to be phased in beginning July 1, 2014. Those increases, however, will depend on the state's economic health at that time."
On Wednesday, the state's psychiatric technicians' union became the second union to announce it had reached a tentative deal with the governor. It calls for more than 6,000 state psychiatric technicians to receive a 4.25 percent raise by 2015.
Nine of the state's 21 bargaining units have yet to strike a deal with Brown. Until then, workers continue to operate under the terms of their expired contracts.
