When an employer alters your job description, it can trigger confusion, frustration, and even financial uncertainty. In Ontario, the law provides clear guidelines on when such changes are permissible and when they may amount to constructive dismissal, a legal concept that empowers employees to seek compensation if their employment terms are unilaterally and fundamentally altered. Here’s what you need to know to protect your rights.

‍

When Can Employers Legally Change Your Job?

Employers in Ontario can modify job descriptions, but significant changes require adherence to specific legal standards. Below are scenarios where adjustments are typically lawful:

1. Minor or Reasonable Adjustments
   Employers may make small changes that align with the evolving nature of your role, such as updating software tools or slightly adjusting responsibilities. These modifications must not fundamentally alter the employment relationship.
2. Mutual Agreement
   If both parties consent to changes—ideally in writing—employers can revise job duties, hours, or pay. For example, agreeing to a temporary role adjustment during a company restructuring is permissible.
3. Contractual Clauses
   If your employment contract includes a flexibility clause (e.g., allowing the employer to modify duties "as needed"), your employer may have legal grounds to make changes, provided the clause is enforceable and reasonable.

When Job Changes Cross the Line: Constructive Dismissal

Substantial unilateral changes to your job without consent may constitute constructive dismissal, effectively treating the employer’s actions as a termination. Key factors include:

‍

1. Fundamental Changes to Employment Terms

Examples of alterations that may trigger constructive dismissal claims include:

• Pay Reductions: Cutting salary, commissions, or bonuses.
• Demotions: Shifting to a lower-ranking role with reduced responsibilities.
• Location Changes: Requiring relocation without contractual permission (e.g., moving an office worker to a remote site).
• Duty Overhauls: Assigning tasks outside your expertise or unrelated to your original role (e.g., requiring a manager to perform manual labor).

‍

2. Employer Retaliation or Pressure

If your employer disciplines, threatens, or pressures you to resign after you reject changes, this constitutes reprisal, a violation of the Employment Standards Act (ESA).

‍

3. Timing Matters

Delaying your objection or continuing to work under new terms may imply acceptance. Employees must act quickly to reject changes in writing to preserve their rights.

Steps to Take If Your Job Description Changes

1. Do Not Resign Immediately
   Resigning without legal advice can forfeit your right to severance or employment insurance.
2. Document and Object in Writing
   Clearly reject changes via email or letter. For example:
   “I do not consent to the proposed changes to my role. These adjustments fundamentally alter the terms of my employment.”.
3. Review Your Employment Contract
   Assess whether flexibility clauses exist. Many are unenforceable if they violate the ESA’s minimum standards.
4. Consult an Employment Lawyer
   A lawyer can determine if you have a constructive dismissal claim, which may entitle you to up to 24 months’ severance under common law, far exceeding ESA minimums.

Employer Obligations and Risks

• Constructive Dismissal Liability: Employers face lawsuits if changes force resignations. Courts often side with employees if modifications are unreasonable.
• New Hire Transparency Rules (Effective July 1, 2025): Employers with 25+ staff must provide written details about job duties, pay, and hours before hiring.
• Termination Clauses Under Scrutiny: Recent cases (e.g., Dufault v. Ignace) highlight that vague termination clauses (e.g., allowing termination “at any time”) may be unenforceable if they risk violating ESA rights.

‍

Key Takeaways

• Legal Changes: Minor adjustments are permissible; major changes require consent.
• Constructive Dismissal: Resignation due to unilateral changes may entitle you to severance.
• Act Fast: Delay weakens your claim. Document objections and seek legal advice promptly.
