The right to refuse work
The Occupational Health and Safety Act (OHSA) gives a worker the right to refuse work that he or she believes is unsafe to himself/ herself or another worker. A worker who believes that he or she is endangered by workplace violence may also refuse work.
The Act sets out a specific procedure that must be followed in any work refusal. It is important that workers, employers, supervisors, members of joint health and safety committees (JHSCs) and health and safety representatives understand the procedure for a lawful work refusal. See link to educate yourself about the OHSA.
