The ballot result, announced on Friday showed that 84%of those who took part in the ballot voted to accept the proposals.
Local government workers took one day of strike action on 30 November 2011, as a result there were scheme specific negotiations, the outcome of which was the subject of this ballot. Unite represents 80,000 members in local government.
Unite national officer, Peter Allenson said: "This is a positive step forward following a one day strike on 30 November and some genuine negotiations with local government employers which have also been signed off by the government.
"Our members took strike action and, as a result they got a better deal. However, the strike action was followed by constructive negotiations which we are pleased ended in an agreement acceptable to our members."
