Did you know that no employer can punish workers for exercising their rights under the Canada Labour Code? This includes dismissal, suspension, lay-off, demotion, financial or other penalty or withholding wages. This is covered in Section 147 of Canada’s Occupational Health and Safety regulations (Disciplinary Action, s.147).
The section also protects workers from threats or actual disciplinary action for providing information to a health and safety officer or anyone working on related things (s.147(b)).
If your employer has threatened discipline or demotion for raising a health and safety issue, contact your union immediately.
