Which of the following is a right of an employee under workplace laws?

The right to refuse unsafe work is a fundamental protection afforded to employees under Canadian workplace laws, specifically referencing health and safety legislation such as the Canada Labour Code and various provincial regulations. This right empowers employees to take a stand against work conditions that they believe pose a risk to their health or safety without fear of repercussions from their employer. The intent is to promote a safe work environment and protect workers from harm.

In contrast, the other options do not align with established legal rights in the same way. Negotiating salary typically involves discussions between employee and employer and does not inherently form a legislated right. Unlimited vacation time is generally not mandated by law and is usually determined by company policy or employment contracts. Finally, while participation in arbitration procedures can be a part of conflict resolution in the workplace, it is not an inherent right under employment laws but rather a process that may be stipulated in an employment agreement or collective bargaining context. Thus, the empowerment of employees to refuse unsafe work stands out as a clear right embedded within workplace legal protections.
