Temporary Reassignment and Duty Changes: Can Your Employer Move You Without Your Consent?

It's Monday morning and your supervisor walks up to you: "We need you in the warehouse for the next two weeks." You normally work on the production floor. Nobody asked for your input. You're not sure those tasks are even in your job description. Can you say no? Do you have to comply without question?

Temporary reassignment — when an employer moves a worker to a different position, department, or set of tasks on a non-permanent basis — is one of the most common sources of conflict in unionized workplaces in Quebec. The confusion stems from a fundamental tension: employers have the right to run their business, but that right is not unlimited. It is shaped by the collective agreement (the negotiated contract between the union and the employer that governs your working conditions), the Act Respecting Labour Standards (ARLS), and well-established arbitration principles. This article explains where the line is drawn.

Management Rights: The Starting Point

In Quebec labour law, employers hold what is known as management rights — the authority to direct, organize, and manage their enterprise. In principle, this includes the ability to assign tasks, temporarily change an employee's duties, and reorganize work teams to meet operational needs.

Arbitrators — the neutral decision-makers who resolve disputes between unions and employers — have long recognized this principle. The logic is straightforward: an employer cannot seek each worker's consent every time an operational adjustment is needed. An unexpected absence, a rush order, a broken machine — things happen, and employers need the flexibility to respond.

But — and this is critical — management rights are not absolute.

Arbitrators have consistently held that management rights are exercised within the collective agreement, not above it. If your collective agreement contains rules about task assignment, the employer must follow them, even if they believe they are acting in the company's best interest.

What Your Collective Agreement May Say

This is where reading your collective agreement becomes essential. Reassignment-related clauses vary significantly from one agreement to another, but here are the most common types:

Job Description and Classification Clauses

Many collective agreements define job titles (also called job classes or classifications) with a corresponding list of duties. If your agreement specifies that a "laboratory technician" performs certain tasks, the employer generally cannot regularly assign you work belonging to a different title without going through the proper process.

Concrete example: Imagine your collective agreement states that employees in the "maintenance worker" classification do not perform supervisory work. If your team lead asks you to supervise a crew for two weeks while the supervisor is away, that could constitute a classification violation — and grounds for a grievance.

Seniority and Assignment Clauses

Some agreements require that temporary reassignments respect seniority order — a worker's rank based on their length of service, which often governs who gets first pick of certain positions or tasks. If the collective agreement says temporary assignments must be offered in seniority order and the employer skips over senior workers to assign you directly, there may be a problem.

Wage Protection and Maintenance-of-Conditions Clauses

Many agreements specify that workers who are temporarily reassigned keep their regular wage — or, if the new tasks are better paid, are entitled to the higher rate. Even without a specific clause, the general principle is that reassignment should not result in a pay cut.

Maximum Duration Clauses

Some agreements set a maximum length for temporary reassignments — for example, 30, 60, or 90 days. Beyond that limit, the employer must post the position or end the reassignment. If your agreement contains this type of clause and the employer exceeds the time limit, that is a clear violation.

When Reassignment Becomes Abusive: Recognized Limits

Even where the collective agreement is silent, arbitrators have developed implied limits on management rights in the context of reassignment. Here are the most commonly recognized problem situations:

Reassignment Used as Disguised Discipline

If an employer transfers workers to a less desirable position, an isolated sector, or significantly worse conditions — in response to a complaint they filed, union activity they participated in, or a specific incident — the reassignment may be characterized as disguised disciplinary action, or even retaliation.

The Act Respecting Labour Standards (s. 122) explicitly prohibits reprisals against employees who exercise a right under the Act. If your reassignment closely follows your challenging a management decision, filing a complaint, or exercising your union rights, the timing can be significant evidence.

Reassignment That Hollows Out Your Position

A well-established arbitration principle in Quebec is that of positional integrity: an employer cannot, under the guise of a temporary reassignment, repeatedly or persistently strip away the essential tasks of your position to the point of hollowing it out. If week after week you are doing something entirely different from what your job title says, it is worth asking whether the situation is truly "temporary."

Reassignment That Causes Serious Prejudice

Arbitrators also examine the real impact on the workers involved: significant geographic relocation, hours that conflict with family obligations, notably inferior working conditions (noise levels, hazards, isolation). A reassignment that causes disproportionate harm relative to the employer's legitimate interest is more likely to be struck down.

Abuse Through Duration or Repetition

A "temporary" reassignment lasting six months, or repeated reassignments of the same worker, loses its temporary character and can be challenged. Arbitrators look at the facts on the ground, not just the label the employer applies.

The Special Case of Medical Reassignment

When workers have functional limitations — due to a workplace accident, occupational disease, or health condition — employers may have an obligation to reassign them temporarily to allow them to continue working under appropriate conditions. This is the duty to accommodate, rooted in the Quebec Charter of Human Rights and Freedoms.

In this context, reassignment is a protective measure, not a punishment. The collective agreement must be interpreted in a way that allows for accommodation, as long as it does not impose undue hardship on the employer.

Separately, for pregnant workers, Quebec's occupational health and safety framework provides specific mechanisms for reassignment to safe duties — an important and distinct protection.

How to Challenge an Improper Reassignment: Step by Step

If you believe your reassignment exceeds permissible limits, here is how to proceed:

1. Document Everything, Right Away

Write down the date you were informed, the tasks being required of you, the name of the manager, and anything said verbally. Keep emails, memos, and written notices. This documentation will be critical if a grievance — a formal complaint filed by the union to enforce the collective agreement — is submitted.

2. Contact Your Union Steward Without Delay

Your union steward (also called a union representative) is your first point of contact. Explain the situation in detail. They can:

• Review the relevant clauses of your collective agreement
• Assess whether the reassignment respects the rules
• Advise you on next steps

Don't wait. Most collective agreements set strict deadlines for filing grievances — often between 5 and 30 days depending on the step. Missing those deadlines can cost you the right to challenge.

3. Try the Informal Route First

In many cases, a direct conversation between the union and the employer is enough to resolve the issue without a formal grievance. Your steward can raise the matter with the manager or human resources to clarify the situation and find a solution.

4. File a Grievance If Needed

If the informal route doesn't work, the union can file a grievance on your behalf. The grievance typically goes through several steps (meetings between union and employer representatives), and if no agreement is reached, it can proceed to arbitration, where an independent arbitrator will decide.

5. Keep Working During the Challenge

As a general rule — except where there is a real threat to your health or safety — comply first, grieve later. This principle, sometimes called obey now, grieve later, means that refusing to follow a management order, even a questionable one, can expose you to disciplinary action. The proper channel for challenging the order is the grievance process, not unilateral refusal.

Conclusion: Knowing Your Rights Is the First Step

Temporary reassignment is not automatically a violation of your rights. In many cases, employers act within their legitimate management rights, and reassignment is part of the normal give-and-take of workplace operations. But those rights have limits — and those limits are written into your collective agreement and the law.

The key is knowing how to read your collective agreement and not hesitating to reach out to your union the moment something feels unfair or out of the ordinary. A grievance filed on time is worth far more than a silent injustice.
