Canada’s second largest airline, WestJet, says it has cancelled at least 150 flights affecting 20,000 passengers beginning Saturday after the union of maintenance workers announced it has gone on strike.

The surprise strike affecting international and domestic flights is happening during the Canada Day long weekend. WestJet said it was “extremely outraged.” The strike came after the federal government issued a ministerial order for binding arbitration on Thursday. That followed two weeks of turbulent discussions with the union on a new deal.

In an update to its membership, the union negotiating committee referenced an order by the Canada Industrial Relations Board that does not explicitly bar any strikes or lockouts as the tribunal undertakes arbitration.

A father who lost 2 sons in a Boeing Max crash waits to hear if the US will prosecute the company

Families of the 346 people who died in two crashes of Boeing 737 Max jetliners are waiting to hear if the Justice Department will prosecute the U.S. aerospace company.

In both the October 2018 crash in Indonesia and the March 2019 crash in Ethiopia, software pitched the plane’s nose down based on faulty readings from a single sensor. Boeing avoided a trial when prosecutors approved an agreement that meant a felony fraud charge they brought could be dropped in three years. California residents Ike and Susan Riffel lost two sons in the Ethiopia crash. Ike Riffel fears that instead of putting Boeing on trial, the government will offer the company another shot at corporate probation.
