CUPE says its members are not backing down.

The union that represents around 10,000 flight attendants plans to continue its strike and challenge an order from the Canada Industrial Relations Board (CIRB).

Minister of Jobs and Families Patty Hajdu sent the dispute into binding arbitration on Saturday and ordered operations to resume.

On Saturday, CUPE National President Mark Hancock spoke to the members

“I’m expected to say stand down.  I’m expected to direct you to go back to work.  I’m expected to end this strike.  That ain’t happening my friends, not  on my watch, not now, not tomorrow, not ever!”

Hancock also proceeded to tear up the CIRB order during the video posted to social media.

He also stated the strike would end when they get a collective agreement that works for their members.

The union is calling the CIRB order unconstitutional, and are inviting Air Canada to come back to the table to negotiate.

The CIRB order stated that flight attendants were to return to work by 2 pm ET on Sunday.
