An Employee Non-Disclosure Agreement (NDA) is a legal document that outlines what confidential or proprietary information an employee can, and cannot share about their employer. This agreement goes beyond the normal workplace expectations of confidentiality in order to protect sensitive details about the company’s products, finances, clients, practices, procedures, and personnel. When an employee signs an NDA before taking a job with a company, it means they understand their role in protecting the company’s confidential information and how it should be handled. By signing an NDA, the employee agrees not to disclose any information learned while working at the company without permission from their supervisor.
