You arrive at work on a Tuesday and your employer tells you the sales territory you have built for eight years is being reassigned, your commission structure is being cut, and you will now report to someone who used to report to you. Nothing in your contract permitted this. They call it a “restructuring.” They expect you to just accept it and keep working. Can they actually do that?
In Alberta, the short answer is often no. The law calls this constructive dismissal, and if the change is serious enough, you have the same rights as an employee who was formally fired without cause.
What Constructive Dismissal Actually Is
Constructive dismissal is not a real dismissal. Your employer has not handed you a termination letter. On paper, you are still employed.
The legal fiction is this: when an employer unilaterally makes a fundamental change to an essential term of your employment contract, the law treats the employer’s conduct as a repudiation of the contract itself. If you do not accept the new terms, you are entitled to treat the contract as at an end, and the law deems you to have been dismissed.
The Supreme Court of Canada developed this doctrine over decades because employers can end a relationship they no longer want using tactics less obvious than a termination letter. A pay cut, a humiliating demotion, or an indefinite layoff can do the same work as firing you, with none of the legal cost to the employer, if the law pretended nothing had happened.
The Test the Court Applies
The governing framework comes from two Supreme Court of Canada decisions: Farber v Royal Trust Co., [1997] 1 SCR 846, which established the foundational test, and Potter v New Brunswick Legal Aid Services Commission, 2015 SCC 10, which refined it into a clearer two-branch analysis.
Under Potter, there are two routes to a finding of constructive dismissal.
The first branch asks two questions. Has the employer breached an express or implied term of the contract? If so, was that breach serious enough to substantially alter an essential term? The test is objective: would a reasonable person in your position conclude the employer had fundamentally changed the deal?
The second branch does not require you to point to a specific breached term. You look at the employer’s course of conduct as a whole. If the cumulative effect shows the employer no longer intends to be bound by the contract, you have been constructively dismissed. This branch captures workplace toxicity, sustained harassment, or a pattern of mistreatment designed to push an employee out.
The Alberta Court of Appeal applied Potter in Kosteckyj v Paramount Resources Ltd, 2022 ABCA 230. An oil and gas employee had her compensation reduced through a base salary cut, bonus elimination, and pension contribution suspension. The Court found the cumulative reduction was a substantial change to an essential term of the contract.
Common Triggers
Not every workplace change qualifies. Employers have legitimate room to reorganize and adapt. The question is whether the change goes to the heart of the deal you agreed to. The following categories come up most often in Alberta claims:
Significant pay reduction. A meaningful cut to salary, commission, bonus structure, or benefits package is the classic case. There is no magic percentage, but a reduction stacked on top of other changes, as in Kosteckyj, can tip a borderline case over the line.
Demotion or material change in duties. Being stripped of responsibilities, having your title downgraded, or being moved to work that is objectively less prestigious or less skilled than the role you were hired for. A change in reporting structure that puts you under someone you previously supervised falls into this category.
Forced relocation. Requiring you to move to a different city or accept a dramatically longer commute, absent a mobility clause in your contract, is usually a fundamental change.
Indefinite layoff. Alberta’s Employment Standards Code, RSA 2000, c E-9, ss. 62 to 64, permits temporary layoffs but caps them at 90 days within a 120-day period in most cases. A layoff beyond the statutory maximum converts into a termination by operation of the Code. Even a layoff within the statutory window can be constructive dismissal at common law if your contract does not authorize layoffs in the first place.
Workplace toxicity, bullying, or harassment. This is where the second branch of Potter does its work. A single incident rarely suffices. But a sustained course of conduct, whether from management or from co-workers that management has failed to address, can cross the line.
Why Timing Matters So Much
This is the part of constructive dismissal that traps employees, and it is the reason you need legal advice before you act, not after.
The employee sits in a narrow window. On one side is the risk of acting too fast. If you resign immediately after a change you believe is a breach, without communicating your position and giving the employer a chance to respond, a court may later find the breach was not yet crystallized or that you overreacted. You lose the claim.
On the other side is the risk of waiting too long. The common law treats prolonged acquiescence as affirmation. If you keep showing up, keep collecting the reduced paycheque, keep performing the new duties, the court may find you accepted the changes. The Alberta Court of Appeal in Kosteckyj reinforced that employees have a reasonable, and quite short, period to object. Weeks, not months.
The practical path: when a substantial change is imposed, you communicate in writing that you do not accept it, you reserve your rights, and you take prompt legal advice. You do not accept the new terms by your conduct. You do not resign without advice. You preserve the claim while you assess it.
What You Can Recover If You Win
The remedies for constructive dismissal are the same as for any wrongful dismissal. You are entitled to common law reasonable notice, or pay in lieu, calculated according to the Bardal factors: length of service, age, character of the employment, and the availability of similar employment. The statutory minimums under the Employment Standards Code apply as a floor.
For a fuller treatment of how reasonable notice is calculated, the duty to mitigate, termination clauses, and damages beyond notice, see my companion article on wrongful dismissal in Alberta. The frameworks are identical once the law treats the employer’s conduct as a dismissal.
One point worth flagging: your duty to mitigate is the same as in any other dismissal. You must look for comparable work. Courts have sometimes held that comparable work includes staying with the same employer under the new terms, if the relationship has not been poisoned and the modified role is not objectively humiliating. This is another reason to get advice before you walk out.
If You Think This Is Happening to You
Keep the documents. Save the email or memo that announced the change, your employment contract, recent performance reviews, and your last several pay stubs. If the change was communicated verbally, write a contemporaneous note of what was said, when, and by whom.
Do not resign on the spot. A resignation made in the moment can be used against you as evidence that you chose to leave rather than being forced out.
Do not sign anything the employer puts in front of you. Employers sometimes follow a unilateral change with a written acknowledgement or release. Those documents can extinguish the claim you are trying to preserve.
Write to your employer. A short letter stating that you do not accept the change, that you consider it a fundamental alteration to your employment, and that you reserve all of your rights can make the difference between a strong claim and a lost one.
Get legal advice before you make the next move. Constructive dismissal cases turn on facts, timing, and how you responded. Alberta’s Limitations Act, RSA 2000, c L-12, gives you two years, but waiting anywhere near that long is usually fatal to the claim for affirmation reasons. Act within weeks.
