About 1,500 Air Transat flight attendants have voted for a mandate for a general strike and voted against the latest offer from their employer, the Canadian Union of Public Employees said on Thursday.
The vote means the flight attendants could launch a strike anytime after July 19, the union said in a statement.
Talks between the flight attendants and the airlines hinge on demands for better pension plans and shorter work shifts.
On April 21, the union asked the Federal Ministry of Labour to appoint a conciliator to assist in the ongoing negotiations.
The union said it hopes to negotiate an agreement and avoid a dispute. The next bargaining sessions will take place next week.
