Can the courts force an employer to retract a dismissal without notice if an employee has not committed a serious breach of contract?

A dismissal without notice or with inadequate notice (or inadequate payment in lieu), other than when an employer is acting in response to an act of gross misconduct on the part of the employee, is a breach of contract. This is referred to as a wrongful dismissal. Although the courts will seldom grant an injunction to restrain a threatened wrongful dismissal or order the re-engagement of an employee who has been wrongfully dismissed, they may award damages to the employee for loss of earnings.
