The state's largest police union voted 1,108-250 in favor of the deal. The electronic voting began Sunday and concluded Friday morning.
The pact still needs approval from the Metropolitan Police Committee on Fiscal Affairs, a board made up of representatives from the city of Las Vegas and Clark County that authorizes police spending.
The committee meets Monday to consider the agreement.
"I think it is a gigantic deal," said Chris Collins, executive director of the union. "It is a huge dollar savings to the city and the county."
