The term ”constructive” dismissal is not specifically provided for in the Unfair Dismissals Act 1977. However, it is a term commonly understood to refer to that part of the definition Section 1(b) of the Act (as quoted below).
(b) the termination by the employee of his contract of employment with his employer, whether prior notice of the termination was or was not given to the employer, in circumstances in which, because of the conduct of the employer,, the employee was or would have been entitled, or it was or would have been reasonable for the employee, to terminate the contract of employment without giving prior notice of the termination to the employer.
