One issue regularly faced by employers is that of employees leaving before working their full notice period. If it is stated in the contract, then technically if an employee does not work their notice, they are in breach of contract and the employer is within his or her rights to sue.

In practice, employers generally do not go down this route due to the relative expense and inconvenience. However an employer is entirely within their rights to withhold pay for the notice not worked if that is an express written term of the contract and also may wish to reflect the fact that notice was not worked in any written reference they may be asked to produce on behalf of the employee in the future.
