The wage offer presented a year ago to 25,000 Alberta Health Services support staff is back on the table.

According to the Alberta Union of Provincial Employees, AHS during mediation this week offered members of the General Support Services unit a one per cent wage increase for each year of a three-year contract.

AUPE president Guy Smith says it's the same offer presented last year to the bargaining unit, which represents a broad range of support staff, from cleaners to IT (information technology) workers of AHS.

That offer was rescinded in January 2014, and replaced by a zero per cent wage increase.

"There's a level of discontent and anger towards Alberta Health Services, which is now translating towards the government itself," said Smith, adding the unresolved contract was a leftover issue from the previous government "that was a massive irritant."

Calling the latest offer a "disappointment," Smith said some members feel let down by the NDP government.

"Many of those members obviously supported the government when they got elected and probably worked on (their) campaigns because they saw this government as supportive of front-line workers," Smith said. "They're not seeing that yet."

Smith said a one percent wage hike doesn't fairly compensate employees who are an important part of the health care team and have been without a collective agreement for almost two years.

Their contract expired in March 2014.

Thirteen thousand auxiliary nurses are also seeking a new collective agreement with AHS.

Their contract expired in March this year.

Premier Rachel Notley has frequently said her government will not attempt to cut costs by slashing jobs in the public service, or by firing teachers and nurses.
