Why Companies Ask Employees to Sign NDAs
Employee NDAs protect company trade secrets, client lists, financial data, and proprietary technology. Unlike Australia, US law on employee NDAs varies significantly by state.
What companies typically protect with employee NDAs:
- Proprietary technology and source code
- Customer lists and contract terms
- Financial data and pricing strategies
- Business strategies and expansion plans
US State Variations: Enforceable NDAs
This is critical: US states vary widely on post-employment restrictions.
- California: Non-competes are largely unenforceable (Business & Professions Code §16600). However, NDAs protecting trade secrets ARE enforceable under UTSA. Focus on NDAs, not non-competes.
- Texas: Non-competes are enforceable if reasonable. NDAs are strongly enforced. You can impose broader restrictions here.
- New York: Non-competes must be "reasonable in geographic and time scope." NDAs are well-enforced.
- Florida: Non-competes are enforceable. Strong NDA protections.
Federal Law: The Defend Trade Secrets Act (DTSA)
Federal trade secret protection makes employee NDAs stronger across all states:
- The DTSA (2016) provides federal remedies for trade secret misappropriation
- Treble damages (3x) are available for willful misappropriation
- Include DTSA language in your NDA for federal protection
- Even in California, where non-competes are unenforceable, NDAs protecting trade secrets are valid under DTSA
Key Employee NDA Clauses for the US
- Definition of Confidential Information: Be specific. Trade secrets, client lists, financial data, strategies, source code.
- During-employment obligations: Employee keeps information confidential while working. This is standard and enforceable.
- Post-employment obligations: 1–3 years after employment is typical. Longer periods are harder to enforce in many states.
- Trade secret status: Explicitly state info is protected under DTSA and state trade secret laws
- Reasonableness: Courts scrutinize overly broad or indefinite restrictions. Be specific about what you're protecting.
- No prevention from working: Clarify the NDA doesn't prevent employee from using general skills or knowledge gained
- Permitted disclosures: Allow disclosure if required by law or court order
State-by-State Quick Reference
California: Strong NDAs, weak non-competes. Your NDA must focus on protecting trade secrets, not preventing competition.
Texas: Strong NDAs and non-competes. You can impose broader restrictions if they're reasonable.
New York: NDAs and non-competes enforced if reasonable in scope and duration. Courts apply a "blue pencil" test (can modify overboard clauses).
Florida: Strong protections for both NDAs and non-competes.
Other states: Generally follow UTSA principles. NDAs are well-enforced; non-competes are scrutinized.
Common Employee NDA Mistakes
Mistake 1: Mixing confidentiality with non-compete language. In many states, overly broad restrictions make the whole clause unenforceable. Keep them separate.
Mistake 2: Indefinite post-employment restrictions. Courts expect reasonable duration. 2–3 years is safe; longer becomes risky.
Mistake 3: Not being specific about what's confidential. Vague definitions are struck down. List categories: trade secrets, client lists, financial data, etc.
Mistake 4: Forgetting DTSA compliance language. Add explicit DTSA language for federal trade secret protection across all states.
