Unfair dismissal

Unfair dismissal is when an employer terminates an employee’s contract without a fair, legal reason or fails to follow proper, fair procedures. A dismissal can only be challenged as unfair if the employee has worked for the employer for two years or more.

What is unfair dismissal?

Unfair dismissal is the termination of an employment contract by an employer (with or without notice of termination), where the reason given for the dismissal is not one of the statutory fair reasons (see below) or it was for one of the statutory fair reasons, but the employer has acted unreasonably in deciding to dismiss for that reason.

Part-time and fixed-term workers must be treated the same way as full-time or permanent employees and be given at least the notice period stated in their contract or the statutory minimum notice period, whichever is longer.
