Air Canada's 10,000 flight attendants may strike due to salary disputes. The Canadian Public Employees' Union (CUPE), which represents this group, recently applied to the federal labor department for mediation and intervention, after the contract expired on March 31, the two sides were still deadlocked after several months of negotiations. The trade union pointed out that the monthly salary of junior flight attendants is only 1951 Canadian dollars, which is far lower than the cost of living, and the airlines have not paid the remuneration for boarding preparation, safety inspection and other work before and after the flight for a long time, resulting in employees working overtime for an average of 35 hours per month. According to the Canadian labor law procedure, the mediator will have a 60-day coordination period, followed by a 21-day mandatory cooling-off period. If no agreement is reached, the trade union may initiate a work stoppage 72 hours after the strike vote. Air Canada responded that it is negotiating through formal channels, emphasizing that passengers can book their trips normally. At present, the impact of the strike on summer travel is not clear, but the results of the negotiations between the two sides have attracted much attention.
