In English law all restraints on trade are contrary to public policy and therefore void. However it is possible to design a covenant that protects the legitimate business interest of an employer. As long as it goes no further than is reasonably necessary to protect the employer's interests, a court will uphold the covenant.
The courts recognise that:

If the employer can demonstrate that it has a legitimate interest to protect then it must go on to show that the covenants extend no further than is reasonably necessary to protect the interest.
Information may come into one of four categories:
Trade secrets will be protected even if there is no express duty of confidentiality.
Confidential information will only be protected during the employment and afterwards if protected by express covenant (competition/solicitation/dealing/confidentiality).
Information which is in the public domain or known to the employee as part of his general skill and knowledge cannot be protected pre- or post-termination.
It is sometimes difficult to distinguish between the first two categories and also the second two. In the latter case the obvious example is the names and addresses of customers.
An express confidentiality clause specifies what information the employer considers to be confidential.
The courts will take into account the following factors:

Employer’s should make sure their contracts of employment have:
This should ensure that an employee is not wrongfully dismissed.
