Almost 150 Winnipeg Airport Authority workers have walked off the job.

Starting at 3 a.m. Monday morning, the members of the Union of Canadian Transportation Employees and the Public Service Alliance of Canada were on strike.

Thomas Linner, regional communications officer for the union, said seven days of negotiations ended at 6 p.m. Sunday when an agreement couldn’t be reached, and the employer walked away from the table.

Marianne Hladun, Regional Executive Vice- President for the Public Service Alliance of Canada, Prairie Region said 25 people were on the picket line as of 4:30 a.m., Monday.

"PSAC and its members are disappointed with the Airport’s decision to not address those issues tabled last October, and which remain unresolved tonight”, Hladun said. "PSAC is committed to a successful strike action, if that is what is necessary to ensure that these important workplace issues are resolved and employees work is protected.”

Approximately 150 employees at the airport—including duty managers, administrative workers, IT staff, and airfield maintenance workers —are represented by PSAC and the Union of Canadian Transportation Employees.

The workers have been without a contract since June 30, 2016 and in negotiations since October 2016.

The WAA said customers will not see a disruption in service.
