California courts mostly take a no prisoners approach to Business and Professions Code section 16600, the statute prohibiting illegal restraints on trade. Courts broadly interpret Section 16600, which states that “every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void,” to invalidate most post-employment non-competes and customer non-solicits, including covenants preventing former employees or their new employers from “hiring” employees of a former employer (so-called “no hire agreements”). But Section 16600 does not bar all post-employment covenants–just those that “restrain” trade.
