Common Employment History Mistakes

Mistake 1: Date Discrepancies

Problem: Dates don't match tax records or LinkedIn Impact: Investigators will find discrepancies Solution: Cross-reference W-2s, tax returns, LinkedIn before submitting

Mistake 2: Gaps in Timeline

Problem: Unaccounted time between positions Impact: Investigation delay, additional questions Solution: Account for every month - even 2-week gaps need explanation

Mistake 3: Missing Short-Term Jobs

Problem: Omitting jobs held briefly Impact: Discovered during investigation, raises honesty concerns Solution: Include ALL employment, even jobs lasting weeks

Mistake 4: Wrong Supervisor Information

Problem: Supervisor no longer at company or wrong contact Impact: Delays as investigator tracks down correct person Solution: Research current contact info, note if supervisor left company

Mistake 5: Vague Reasons for Leaving

Problem: Generic explanations like "personal reasons" Impact: Raises red flags, requires follow-up Solution: Be specific but professional ("accepted position with higher salary")

Handling Difficult Employment Situations

Terminated for Cause

Situation How to Handle
Fired for performance State factually, don't be defensive
Fired for misconduct Disclose honestly, explain lessons learned
Mutual separation Explain circumstances
Laid off Clearly note "Reduction in Force"

Example disclosure for termination:

"Terminated due to policy violation regarding [brief description]. Have since completed [relevant training/changed behavior]. No similar issues in subsequent employment."

Company No Longer Exists

Situation Solution
Company closed Note "Company no longer in business"
Company acquired List original name, note acquisition
Records unavailable Provide best information, note limitation

Verification alternatives:

  • Former coworkers
  • W-2s or tax records
  • Pay stubs if retained
  • Professional references from that time

Can't Remember Supervisor

Situation Solution
Don't recall name Research LinkedIn, company directory
Supervisor deceased Note "Deceased" with approximate date
No direct supervisor List manager or HR contact
Can't locate supervisor Provide last known info, note efforts made

Classified Employment

For jobs involving classified information:

  • List employer normally
  • Use unclassified job title
  • Note "Classified duties - details available to cleared investigators"
  • Don't disclose classified program names in unclassified sections
