• Usually gross misconduct

Examples

Investigation and Process

Employer's Investigation

Should establish:

1. What was disclosed - nature and extent
2. To whom - recipient of information
3. How - method of disclosure
4. When - timing and circumstances
5. Intent - deliberate or accidental
6. Harm caused - actual or potential damage

Fair Process

Even for serious breach:

• Suspend if necessary (not punishment)
• Investigate thoroughly
• Collect evidence
• Invite to disciplinary hearing
• Allow to respond
• Consider explanation
• Make reasoned decision
• Offer appeal

Your Explanation Matters

Tribunal will consider:

• Was it truly confidential?
• Did you know it was confidential?
• What was your intent?
• What harm was caused?
• Were there mitigating factors?
• Was it whistleblowing?

When Dismissal May Be Fair

Clear Gross Misconduct

Fair dismissal if:

• Information clearly confidential
• Deliberate or reckless breach
• Serious potential or actual harm
• Fair investigation conducted
• Reasonable belief you did it
• Proper process followed
• Sanction proportionate

Examples

Scenario	Why Fair
Sold client list to competitor	Deliberate, serious harm
Downloaded trade secrets before leaving	Clear intent to misuse
Shared financial data with press	Serious reputational harm
Gave competitor access to systems	Fundamental breach

When Dismissal May Be Unfair

Minor or Technical Breaches

Dismissal disproportionate for:

• Accidental minor disclosure
• Information not truly confidential
• De minimis breach
• First offence with no harm
• Training issue not disciplinary

Process Failures

May be unfair if:

• No proper investigation
• Assumed guilt
• No hearing or right to respond
• Ignored mitigation
• Inconsistent treatment
• Pre-determined outcome

Examples

Scenario	Why May Be Unfair
Mentioned client name in casual conversation	Trivial, no harm
Left document on desk briefly	Careless but minor
Unintentional email cc error	Accident, minimal risk
Information already public	Not actually confidential

Mitigation and Defences

Arguments to Raise

• Information not actually confidential
• Already in public domain
• Didn't know it was confidential
• Accidental not deliberate
• No harm caused
• Whistleblowing disclosure
• Following instruction
• Long service and clean record

Reducing Severity

Factors that may reduce sanction:

• Genuine mistake
• Immediately reported it
• Took steps to mitigate
• Cooperation with investigation
• Remorse and understanding
• Training gap not malice

After Employment Ends

Continuing Obligations

Confidentiality duties continue after:

• Employment ends
• For genuinely confidential information
• Trade secrets protected indefinitely
• Other information for reasonable period

Breach After Leaving

Former employer can:

• Seek injunction to prevent use
• Claim damages
• Report to new employer
• Take legal action

Practical Examples

Accidental Breaches

Email to wrong recipient: Accidentally sent confidential quote to competitor instead of client.

• Immediately reported error
• Took steps to retrieve
• First offence
• Likely warning not dismissal

Careless Breaches

Left laptop on train: Unencrypted device with customer data lost.

• Serious data breach
• Violated clear policy
• Potential GDPR penalties
• Likely dismissal fair

Deliberate Breaches

Forwarded emails to personal account: Downloaded client lists before starting with competitor.

• Clear premeditation
• Intended to use for benefit
• Serious breach of trust
• Definitely gross misconduct
