If your state as an employer allows a non-compete obligation, it must be used and created separately from the non-disclosure agreement. Another reason for a separate agreement is that most states pass laws prohibiting contracts that do not allow a person to look for work. Therefore, if the laws change, any former employee would be prohibited from disclosing trade secrets. If you need help with confidentiality agreements, you can post your question or concern on the UpCounsel marketplace. .
