When you've worked hard to build a company, you want to protect your business and your client base from unfair competition by a former employee. While the Courts recognize that businesses need to protect their interests, it also recognizes that employees have a right to work and also to compete.
The Courts have issued strict standards regarding the enforceability of Non-Compete Agreements, also known as restrictive covenants. If the covenant is not properly drafted the courts will find it to be null and void.
