AUGUSTA — A pair of unions has agreed to contract extensions but the largest group of unionized state employees in Maine was unable to reach an agreement before the contract expired on June 30.

Gov. Paul LePage said today the American Federation of State, County and Municipal Employees Union ratified a one-year extension for 1,000 employees. And the state police negotiating committee agreed to a two-year contract extension that will be voted upon in the coming week.

But the largest union, the Maine State Employees Association, has failed to reach an agreement.

Negotiations ended just before midnight with MSEA offering a two-year extension on the current terms and the state countering with a one-year extension under different terms. One of the outstanding issues is compensation for workers engaged in union activities.
