It is impossible to predict ahead of time exactly what a third party will do if you compete against them using insider information. So, the following information is only a general list of possible claims. Not everything may apply to you, and of course additional claims could be brought depending on the particular facts of the case. __Good faith and fair dealing:__ The implied covenant of good faith and fair dealing is a general presumption that the parties to a contract will deal with each other honestly, fairly, and in good faith. __Non-compete agreements:__ Many employment contracts contain non-compete agreements that restrict employees from competing with their former employer for a certain period of time after leaving the company. Often, these contain non-disclosure agreements that may prohibit you from using any information you have learned in your course of employment. __Trade secrets:__ Trade secrets are any type of information that gives a company a competitive advantage, such as customer lists, pricing information, or trade secrets. __Misappropriation of confidential information:__ Even if you do not have a non-compete agreement or trade secrets, you may still be liable for misappropriation of confidential information if you use or disclose confidential information.
