Many thanks for your patience. If there is a written contract in place and it contains a specific notice period clause an employee must give if they wanted to resign, they will be contractually bound by it. Therefore, if the employee fails to honour this notice period they will be acting in breach of contract. Whilst no one can physically force them to work through their notice period, it would instead allow the employer to sue them for compensation for losses/damages resulting from their breach.
In reality such claims are very rarely made. This is mainly due to the costs and time involved, also the relatively small damages that can be recovered. The employer has to show that actual losses have been incurred and often that is not easy to do. The most common damages they would claim for are if they have to engage temporary cover for the employee’s duties and the extra wages they have to pay them or recruitment fees for recruiting a replacement at short notice.
So whilst there is no way of predicting whether the employer will take this any further, chances are that they will not. A more likely outcome is that the employer refuses to provide a reference in the future or if they do, it could mention that the employee had breached their contract.
If no contractual notice period clause exists, an employee who has been continuously employed for at least one month is required to give a minimum notice period of one week in order to terminate their employment.
It is therefore best to try and negotiate a mutually acceptable notice period that would suit both parties. However, if that is not possible and there is a pressing need to leave early, that is still a possibility, subject to the risks identified above.
Finally, there are circumstances when an employee may be entitled to leave with immediate effect and without honouring their notice period. This occurs when an employer has committed a serious breach of contract first. The whole contract, including the notice periods, then becomes immediately void and the employee would be treated as being 'constructively dismissed'. So if there are reasons to believe the employer has acted in breach of contract, whether a breach of an express contractual term, or other breaches, this reason can be relied on in order to leave with immediate effect. The most relevant one for you would be the on-payment of wages which you can potentially rely on to argue constructive dismissal .
