The legal starting point is that a contractual term restricting your activities after termination of your employment is not regarded as valid because it prevents you earning a living. This is because it is in the public interest that people should be allowed the freedom to work and there should be a healthy market with healthy competition.
A (former) employer can however enforce ‘reasonable’ restrictions on your activities when you leave employment, on a limited basis, as long as the employer can demonstrate the following:
If you are planning to take a new role, or start a business, that you are concerned might breach the clauses in your contract, don’t ignore it and hope no-one will notice! Take advice from our specialist employment team to get an opinion on whether the restrictions are likely to be enforceable or not.
This is a tricky area. Getting it wrong can result in claims against you, high legal fees, damages being awarded (to be paid to your employer) and/or injunctions stopping you doing what you wanted to do.
