Nursing and support staff at Monterey Place seniors facility in northeast Calgary have voted in favour of a contract that provides for wage increases over the next four years.

The 90 members of the Alberta Union of Provincial Employees have been on the picket line since June 26, 2012 — making it the longest contract dispute in the union's history.

"This agreement will see a major improvement in the employees' compensation," said union president Guy Smith in a written statement.

The four-year agreement, which was proposed by a mediator, will see the hourly wage for health care aides increase by up to 44 per cent by the end of the contract.

Pay for licensed practical nurses will increase by as much as 40 per cent over four years, and wages for some support staff will go up by as much as 20 per cent.

According to the AUPE, the wage increases will still leave the workers below the industry standard.

"It wasn't an easy decision to accept the mediator's recommendation, but after nearly a year, these brave dedicated members needed to get on with their lives," said Smith.

The new contract expires in 2016.
