Rural/Metro Medical Service EMTs and paramedics have voted to approve a new four-year agreement, following last week’s 21-hour negotiating session that ended a strike lasting less than eight hours.

The rank-and-file workers’ approval came in a weekend vote that ended late Sunday night, officials said.

The agreement, retroactive to July 1, affects approximately 400 EMTs and paramedics.

Brian Lawson, Rural/Metro’s public-affairs director, said the agreement provides average wage increases of 5 percent in the first year, followed by 2 percent, 3 percent and then 4 percent. The new agreement also raises the average hourly wage of EMTs and paramedics to $14.10, with annual earnings projected to be 12 percent higher than the national average, the company stated.

Officials from Teamsters Local 375 could not be reached to comment on the specific vote totals.
