Jobs evolve, and employers are allowed to manage. But there is a difference between reasonable change and quietly rewriting your role into something you never agreed to. When a change is fundamental, the law can treat it as if you were dismissed.
✅Quick answer. Your employer can make reasonable adjustments to your duties. But if it fundamentally changes your role, responsibilities, or status without your agreement, for example stripping your core duties or demoting you in function, that can be a constructive dismissal, letting you treat the job as over and claim severance. Minor or temporary changes usually do not qualify.
Can your employer change your duties?
Within limits, yes. Reasonable changes that come with a normal, evolving job are part of an employer's right to manage. What they cannot do is unilaterally impose a change so significant that it goes to the heart of your employment, effectively replacing the job you agreed to with a different one.
What kinds of changes cross the line?
- Stripping your responsibilities or removing your core duties.
- A demotion in function, even if your pay stays the same, such as losing management or a meaningful part of your role.
- A drastic change in the nature of your work that you did not sign up for.
- Being sidelined, cut out of decisions, or given busywork to push you out.
A change like this can be a constructive dismissal even without a pay cut, because your role and status are themselves fundamental terms of the job.
That principle is long-settled. In Reber v. Lloyds Bank International Canada (1985), the court confirmed that a demotion to a role of lesser responsibility can be a constructive dismissal even when the pay is unchanged, because the loss of status and responsibility itself changes the essential bargain. In Chandran v. National Bank (2011 ONSC 777), a bank manager of 18 years was subjected to unjustified discipline and then offered only lower-grade positions; the court held he was not required to accept a demotion that meant humiliation and loss of trust, treated the situation as a dismissal, and awarded 14 months of notice. You do not have to swallow a demotion to keep a paycheque coming.

What usually is not enough?

- 1.Do not resign on the spot, and do not simply accept the change as normal.
- 2.Put your objection in writing and reserve your rights.
- 3.Keep records of your old duties and the new arrangement.
- 4.Get advice before you decide. A free review can tell you whether the change is a constructive dismissal.
