A Contractor Employee Non-Disclosure Agreement (NDA) is an agreement between a contractor and an employer that binds the contractor to keep certain confidential information belonging to the employer secure and not to use or disclose it without the employer’s permission. There are two main types of Contractor Employee Non-Disclosure Agreements: unilateral and mutual. A unilateral agreement is one-sided, with the employer providing confidential information to the contractor without the contractor having to provide any confidential information to the employer. A mutual agreement is a two-way agreement, with both the employer and the contractor exchanging confidential information. Both types of agreements must include specific provisions, such as the type of confidential information being exchanged, the duration of the agreement, and the consequences of a breach.
