I a non-unionized employee for the provincial government in Ontario and have been working from home since March 2020. Now the requirement is to go back to work 5 times a week. Preferably, I would like to keep my job but continue WFH. What are my options?

It is possible that your employer's decision to make you return to work at the office constitutes a constructive dismissal. However, unless your employer agrees to continue allowing you to work from home, your potential recourse is to allege constructive dismissal and pursue severance pay. There is no way to force your employer to continue to allow you to work from home. Please contact our firm if you would like to discuss your potential options in more detail.
