Canada’s government forced Air Canada and its striking flight attendants back to work and into arbitration Saturday after a work stoppage stranded more than 100,000 travelers around the world during the peak summer travel season.

The decision by the union representing the 10,000 workers means that travel chaos will continue for at least a second day. Air Canada said it had suspended its reopening plan until Monday evening.

More than 10,000 Air Canada flight attendants will continue their strike despite back-to-work orders from the Canadian government, the Air Canada component of the Canadian Union of Public Employees said Sunday.
