California treats confidentiality agreements very differently from non-competes. Under Business and Professions Code §16600, California voids most post-employment competition restraints, yet it fully enforces NDAs that protect genuine trade secrets, and the state has its own Uniform Trade Secrets Act at Civil Code §3426. Draft the NDA so it reads as pure confidentiality and never strays into restraint of trade, because California courts will scrutinize any clause that functions as a backdoor non-compete and may invalidate it.
Texas enforces confidentiality agreements readily and adopted the Texas Uniform Trade Secrets Act (Civil Practice and Remedies Code Chapter 134A). Texas courts uphold reasonable confidentiality terms and even view a promise to disclose proprietary information as valid consideration for a current employee's signature, which makes mid-employment NDAs easier to enforce here than in many states.
New York stands out as one of the few jurisdictions without a statutory trade secret act, relying instead on common law shaped by decades of case law and the Restatement of Torts. Courts apply a multi-factor test to decide whether information truly qualifies as secret, so a precise contractual definition does real work in New York. The state also recently moved to restrict certain employer practices around employee speech, making careful drafting more important than ever.
Florida offers strong protection through the Florida Uniform Trade Secrets Act (Chapter 688, Florida Statutes) and a generally employer-friendly posture. Florida courts will enforce confidentiality obligations and, unlike with non-competes, do not require the tight durational limits the state imposes on movement restrictions, giving employers more latitude in how long the secrecy duty runs.
