Overview

Non-Disclosure Agreements in California

California has some of the most employee-friendly NDA laws in the country. Under Cal. Bus. & Prof. Code § 16600, any contract that restrains a person from engaging in a lawful profession, trade, or business is void — with very narrow exceptions. This means that NDAs cannot prevent employees from working for competitors after employment ends. California does protect true trade secrets under the California Uniform Trade Secrets Act (CUTSA), but employers cannot use NDAs to prevent employees from using general skills and knowledge gained during employment.

Yes, employers can require NDAs to protect trade secrets. However, they cannot require employees to sign agreements that prevent disclosure of wages, working conditions, or potential legal violations.
