WINNIPEG — Around 150 workers at Winnipeg’s Richardson International Airport could walk off the job at midnight Friday after voting earlier this week in favour of a strike.

The employees – members of the Public Service Alliance’s Union of Canadian Transport Employees – include duty managers, administrative workers, various tradespeople, IT workers, airfield maintenance and labourers.

A breakdown of Monday’s strike vote was not released by the union.

The workers staged a demonstration at the airport last week to draw attention to their contract dispute before management and union officials met with a federal mediator.

The union says its priority is to save jobs and stop management from contracting out work, as they say other union jobs at the airport have been contracted out.

Both management and union officials have said the travelling public is unlikely to notice a difference if there is a strike because of agreements to provide essential services.
