A reminder here that arbitration always favours the abuser -- which, in the case of a corporate/individual dispute, is almost invariably the corporation.
Background: Air Canada decided to skirt labour laws by saying that flight attendants aren't on the clock until the plane leaves the runway. This, combined with the fact that the contractual pay did not keep up with inflation, has led to a strike against the company, well-known for being abusive and dismissive towards employees and customers alike.
12 hours after the strike began, the Liberal government, known well for sucking off Air Canada's fuel line, declared that forced arbitration would need to be done.
The union saw that arbitration would, by its nature, favour Air Canada and fuck over their members, and said, 'No.' So good on them.
To those who've had their flights cancelled by Air Canada, remember that they legally have to reimburse you for a flight on another airline unless you accept another option, so don't accept a refund when the replacement might be more expensive.
