An arbitrator has ruled that Air Transat cabin crew members are not permitted to use cannabis, whether on duty or off, reinforcing the airline's safety policy. This decision, made by arbitrator Nathalie Massicotte, supports Air Transat's stance that employees in high-risk positions, such as flight attendants, must remain free from any potential impairment. The airline implemented this policy following the legalization of cannabis in Canada in 2018, citing safety concerns. The Canadian Union of Public Employees (CUPE) challenged the policy, arguing it infringed on employees' privacy rights. However, the ruling found the policy to be reasonable, emphasizing the crucial safety responsibilities of cabin crew members and the uncertain effects of cannabis. The ruling noted that while alcohol is prohibited 12 hours before a shift, the residual effects of cannabis can last longer and vary significantly among users. Union president Marie-Hélène Nadeau expressed ongoing concerns regarding the policy's implications for members' privacy and the potential for disciplinary action for cannabis use days prior to work.
