This defines a situation whereby an employee presents his/her case to an Employment Tribunal on the basis that the employer has breached their contract to such a fundamental extent that they could not be expected to work in that position any longer. Their complaint is one of constructive dismissal alleging that they were entitled to treat the contract as having ended. Only employees with one year's service will be able to complain of constructive dismissal, and they will be entitled to their loss according to how long they have remained out of work, as at the date of the Tribunal.
