Air Canada will resume flights Monday evening, claiming the union illegally directed flight attendants to defy a return-to-work order.

Flight attendants are demanding better wages and compensation for unpaid work. Currently, Air Canada only compensates flight attendants for the time they are in the air, but its attendants are seeking pay for the work they do before take-off and after landing, too.

The Canadian government wants an arbitrator to impose a deal to end Air Canada strike that's stranded airline passengers.
