If your employer has made changes to the terms and conditions of your employment, such as your pay, duties & responsibilities, or location of work, you may have a claim for constructive dismissal. A constructive dismissal means that by changing a fundamental aspect of your employment without your consent, an employer has terminated your employment under law, which could enable you to quit and sue as if you’ve been fired.  

Each situation involving a constructive dismissal is unique, and it is important that you consult with a lawyer right away if any fundamental change happens to your employment.
