Your pay and hours are core terms of your job, not things an employer can rewrite at will. When a company imposes a serious cut without your agreement, it may have effectively ended the deal you signed up for, which the law can treat as a dismissal.

Quick answer. Not significantly, and not without your consent. A substantial, unilateral cut to your pay, hours, or commission structure can be a constructive dismissal, which lets you treat the employment as terminated and claim severance. Small or genuinely temporary adjustments may be permitted, and the ESA sets a wage floor, but a major cut is a serious legal event.

Can your employer reduce your pay?

Not by a meaningful amount without your agreement. Pay is a fundamental term of your employment. A significant unilateral pay cut is one of the clearest examples of constructive dismissal. Your employer also cannot reduce your pay below minimum wage or below what the ESA otherwise requires. The Supreme Court set the test in Farber v. Royal Trust Co. ([1997] 1 SCR 846): a constructive dismissal happens when an employer makes a substantial, unilateral change to a fundamental term such that a reasonable person in the employee's position would feel the essential terms of the job had been changed. A serious cut to your compensation is exactly that kind of change.

How big a cut has to be to matter

There is no magic percentage, but the larger and more permanent the cut, the more likely it crosses the line. A small, temporary trim during a genuine downturn may not be enough on its own; a serious, lasting reduction usually is. Courts look at the overall impact on you and whether the change strikes at the heart of your compensation.

A striking example is Russo v. Kerr Bros. Ltd. (2010 ONSC 6053). A long-service employee had his total compensation cut roughly in half, from about 114,000 dollars to around 60,000 dollars, when his employer restructured. The court held this was a constructive dismissal even though the company was in genuine financial difficulty: real hardship may explain why an employer wants to cut pay, but it does not give the employer the right to impose that cut on an employee without consequences. A reduction of that magnitude goes to the root of the contract.

What about cutting your hours?

A significant reduction in your hours is a reduction in your pay, and the same analysis applies. Cutting your hours to zero is effectively a layoff, which is not automatically lawful: unless your contract allows it or you agree, it can be a constructive dismissal from the start. See your rights when laid off.

What about commission or bonus changes?

Changing the structure so you earn materially less, for example slashing commission rates, moving the goalposts on targets, or removing a bonus you relied on, can also be a constructive dismissal if the impact is significant. The label the employer uses matters less than the real effect on your income.

⚠️Do not quit, and do not just accept it. If you simply keep working under the new terms as if nothing happened, you may be found to have accepted the change. If you quit over a cut that was not big enough to qualify, you may get nothing. Object in writing and get advice before deciding.

What can you do about a pay or hours cut?

  1. 1.Get the change in writing, including the amount and whether it is permanent.
  2. 2.Put your objection in writing and reserve your rights.
  3. 3.Do not resign in the moment.
  4. 4.Get advice on whether the cut is a constructive dismissal. A free review tells you whether you can claim.
