Non-compete cases are very fact specific. Whether the agreements have similar language or not, the underlying facts will determine how the case is decided. The Court will look at the industry, the work actually done and whether trade secrets or confidential information is involved. Other considerations include confidential customer lists and if areas of special proprietary or unique services were rendered.
The phone rings and your client tells you he has been served with a summons and complaint alleging he has violated a non-compete agreement he had with his former employer. Most employees unless they are at the higher levels of compensation will not seek private counsel to review these agreements before signing them. Unfortunately your client did not understand the implications of the agreement when signing it and did not consult counsel when starting a new job with a competing company or opening their own company.
