Security guards at Trudeau Airport are planning weeks of strike action after they firmly rejected an offer from management.

100 percent of staff voted to reject the demand to accept pay cuts of several thousand dollars per year.

The members of the SAS-ADM union must, however, maintain essential services, and are only allowed to go on strike for 30 or 60 minutes per day.

140 security guards at the airport recently began working for Garda, after that company won the contract to provide security at Trudeau International.

The union is asking airport management to get involved in contract negotiations, saying the only way Garda was able to tender the lowest bid and win the airport security contract was through a plan to cut salaries.
