Confidentiality Clauses in Employment Contracts
How confidentiality clauses protect business information. Learn what can be covered and how to enforce confidentiality obligations.
Confidentiality clauses protect a business's sensitive information during and after employment.
Implied Duty vs Express Clause
Implied Duty (Automatic)
All employees have an implied duty to:
- Not disclose confidential information during employment
- Not use confidential information for personal gain
- Act in good faith toward the employer
Limitation: After employment ends, the implied duty only covers trade secrets, not general confidential information.
Express Confidentiality Clause
A written clause provides:
- Clear definition of what's confidential
- Protection beyond trade secrets
- Extended duration after employment
- Specific remedies for breach
What Can Be Protected?
Trade Secrets (Highest Protection)
- Secret formulas or recipes
- Proprietary manufacturing processes
- Source code and algorithms
- Research and development data
Trade secrets are protected indefinitely, even without a written clause.
Confidential Information
- Customer and supplier lists
- Pricing strategies
- Business plans
- Financial information
- Marketing strategies
- Employee information
Requires express clause for post-employment protection.
Information That Cannot Be Protected
- Skills and general knowledge gained
- Information already public
- Information received from third parties
- Information required by law to disclose
Drafting an Effective Clause
Define Confidential Information
Be specific about what's covered:
"Confidential Information includes but is not limited to: customer lists and contact details, pricing information, business strategies, financial data, technical specifications, and any information marked as confidential."
Scope of Obligations
Specify what the employee must and must not do:
"The Employee shall not, during or after employment, use or disclose any Confidential Information to any person except as required for their duties or with written consent from the Company."
Duration
State how long obligations last:
"The obligations in this clause shall continue for a period of [2-5] years following termination of employment, except for trade secrets which shall be protected indefinitely."
Exceptions
Include necessary carve-outs:
"These obligations do not prevent disclosure required by law, court order, or regulatory authority, or disclosure of information that becomes publicly available through no fault of the Employee."
Whistleblowing Protection
Confidentiality clauses cannot prevent employees from:
- Reporting criminal activity to authorities
- Making protected disclosures under whistleblowing law
- Reporting health and safety concerns
- Reporting discrimination or harassment
- Disclosing to legal advisers
Any clause that attempts to prevent protected disclosures is void and unenforceable.
Enforcing Confidentiality
During Employment
- Verbal warning
- Written warning
- Disciplinary action up to dismissal
- Injunction to prevent further disclosure
After Employment
- Send cease and desist letter
- Seek interim injunction
- Claim damages for losses
- Account of profits
Remedies for Breach
| Remedy | Purpose |
|---|---|
| Injunction | Stop ongoing/threatened disclosure |
| Damages | Compensate for losses suffered |
| Account of profits | Recover gains made by former employee |
| Delivery up | Return of confidential materials |
Practical Protection Steps
Beyond the contract clause:
- Mark documents as confidential
- Limit access to need-to-know basis
- Use NDAs with third parties
- Secure systems with password protection
- Exit procedures to recover materials
- Remind leavers of ongoing obligations

Frequently Asked Questions
- Is confidentiality implied in employment contracts?
- Yes. Employees have an implied duty of confidentiality during employment. However, this implied duty is weaker after employment ends, so explicit confidentiality clauses are important for ongoing protection.
- What information can confidentiality clauses cover?
- Confidentiality clauses can cover trade secrets, customer lists, pricing information, business strategies, technical know-how, and other commercially sensitive information. They cannot prevent disclosure of illegal activities or public interest matters.
- How long do confidentiality obligations last?
- For trade secrets, protection can last indefinitely. For other confidential information, courts may limit enforcement to a reasonable period, typically 2-5 years after employment ends.
