I have an employment contract stating my work location to be downtown. I have been told however that I will now be working for a satellite office which is 20KM away.  This may not seem like a huge distance but with the traffic in Toronto during the morning and evening commute times, I would be in my car for 45 minutes longer in each direction.  This seems unfair.  Do I have any right to reject the change?

You can reject changes to your job that fundamentally alter your working conditions.  This is known as a constructive dismissal.  A new work location is sometimes considered a fundamental change but it will depend on the circumstances.  If your contract guaranteed you a downtown Toronto location and that was important to you, the employer’s decision to change that term should be considered a fundamental alteration.

In a situation like this, you should make it known to your employer that you reject the change.  If the employer will not resume your employment at the downtown location, and insists that you work from the satellite office, you may be able to consider yourself as constructively dismissed, leave the workplace and sue for lost wages while you look for other work.
