Did Your Job Change? When a Shift in Responsibilities Becomes Constructive Dismissal

Not every change to your job crosses the legal line into constructive dismissal. But some do. And knowing the difference matters, whether you are an employee deciding whether to walk away or an employer managing a reorganization.

Two Alberta cases illustrate the contrast well. Both involved employees whose job responsibilities changed significantly. One claim failed. One succeeded. The difference came down to whether a reasonable person in the employee’s position would have felt their essential terms of employment were being fundamentally altered.

If your core duties have been reassigned without your agreement, you may have a claim for constructive dismissal.

The Legal Test: Substantial Change to Essential Terms

The Supreme Court of Canada set out the governing principle in Farber v. Royal Trust Co., [1997] 1 SCR 846. Constructive dismissal occurs when an employer unilaterally makes a fundamental or substantial change to an employee’s contract of employment that violates the contract’s terms. The question is whether a reasonable person in the same situation as the employee would have felt that the essential terms of the employment contract were being substantially changed.

Importantly, the analysis is objective, not subjective. It is not enough that the employee felt demoted or disrespected. The court asks what a reasonable person would have concluded, based on the full picture of what changed and what remained the same.

When the Claim Succeeded

Morrison v. Alberta Distillers Ltd. [1994] A.W.L.D. 512 involved a long-tenured employee who had spent nearly 30 years with the company, rising to the position of Head, Technical Services. In 1989, after expressing a desire to wind down, the employee negotiated a new arrangement with the company president that formalized his role: independent technical and scientific work, new product development, training, preservation of technical data, and troubleshooting. He was not required to supervise people. He reported to a vice-president. He was part of senior management.

Then, in September 1992, the employee was called in and told, on a take-it-or-leave-it basis, that his position no longer existed and he was being offered the role of Production Superintendent. That role involved managing three departments, hands-on supervision of staff, and reporting to a plant manager rather than a vice-president. Technical services work would be accommodated only “when time permits.”

The court found this to be both a fundamental breach of the negotiated contract and, in the alternative, a constructive dismissal. The position offered was a demotion. The employee’s carefully negotiated independence, his scientific focus, his place in senior management, and his freedom from supervisory responsibilities were all stripped away simultaneously, without warning or consultation. The fact that the defendant believed it was offering an attractive opportunity with more budget and reporting staff did not change the analysis. The question was whether the change was a demotion from this employee’s perspective in his circumstances, and it clearly was.

The employee’s refusal to accept the new position was found to be entirely reasonable. He was awarded 18 months of notice, based on his age, his years of service, his senior position, the high-handed manner of the dismissal, and the difficulty he would face finding comparable work.

When the Claim Failed

Saik v. Canadian Natural Resources Limited, 2001 ABQB 986 arose from a corporate merger. The employee was a senior geological technician at one company when it merged with the defendant. On a review of staffing, the defendant recognized the employee’s computer expertise and offered to continue his employment at the same salary.

The employee objected to several changes: the word “senior” was dropped from his title, he would report to a district geologist rather than a senior manager, he would no longer do investor relations work, and the computer provided to him was of lesser quality than his previous one. After four days on the job, he quit and claimed constructive dismissal.

The court dismissed the claim. The judge found that the changes were reasonably explained by the need to fit into a different corporate structure, not by any intent to demote or denigrate the employee. On the title change, the defendant simply did not use the “senior” designation for anyone. The employee was, in fact, the highest paid person in his classification. On investor relations, the defendant had dedicated staff for that function, so it was not available to anyone in his role. On the reporting structure, the substance was largely the same despite the difference in titles.

The court held that a reasonable person would have understood these changes as reflecting the new corporate organization, not a fundamental alteration of their essential employment terms. There was also no hostility, embarrassment, or confrontation between the employee and the new employer.

The court went further, finding that even if constructive dismissal had been established, the employee failed to mitigate his damages. Given that the salary was unchanged, the working conditions were not substantially different, and the workplace was not acrimonious, a reasonable person would have stayed in the role while looking for something better. Severance entitlements and mitigation are closely linked, and understanding both matters. For a broader overview, see our guide to severance pay in Alberta.

What These Cases Tell Us

A few key lessons emerge from comparing these two outcomes:

• Context matters. A merger that reorganizes job titles and reporting structures is a very different situation than a unilateral ultimatum that eliminates a negotiated role entirely.
• Compensation is not the whole picture. In both cases, the employer offered comparable or increased remuneration. But in Morrison, the court recognized that salary alone does not define the essential terms of employment. Autonomy, seniority, reporting relationships, and the nature of the work itself are all part of the contract.
• How a change is made matters as much as what changes. The court in Morrison was critical of the take-it-or-leave-it ultimatum with no prior warning, no consultation, and no options. Even if the new role might have been acceptable to a different employee, the manner of its imposition was a factor in the outcome.
• Failing to stay can cost you. In Saik, the court found the employee should have continued working while looking for another position. Walking away too quickly, when the changes were not truly fundamental, may eliminate a damages claim entirely.
• Not every change is a constructive dismissal. Businesses reorganize. Mergers happen. Roles evolve. The law does not require employers to freeze a job description in place indefinitely. But it does require that fundamental changes to essential terms be negotiated, not imposed. For a deeper look see our full breakdown on constructive dismissal law in Alberta.

Facing a Change at Work? Get Advice Before You Act.

If your employer has significantly changed your role, title, reporting structure, or responsibilities, it is worth getting legal advice before deciding how to respond. Whether those changes rise to the level of constructive dismissal depends on the specific facts of your situation.

Acting too quickly, as in Saik, can undermine your claim. But accepting a demotion without objecting can also affect your rights. The window for taking action is not unlimited.
