Investigating Employee Absenteeism: Checking genuine sick leave
Employee absenteeism is more than just an HR issue — it can become a serious business risk. While most absences are genuine, a pattern of unexplained or false sick leave may point to deeper problems like fraud, misconduct, or abuse of company policies.
At Corporate Investigations, we help UK employers get to the truth behind repeated or suspicious staff absences. Whether it’s about protecting productivity, upholding company policy, or gathering evidence for disciplinary action, we deliver results — evidence to a court standard.

Why Does Absenteeism Matter?
When employees repeatedly fail to show up without good reason, the impact can be significant.
It affects:
- Team morale
- Project deadlines
- Operational efficiency
- Business costs
- Reputation, especially in client-facing roles
- Worse still, false absenteeism can be a cover for:
- Working elsewhere while claiming sick pay
- Moonlighting with competitors
- Faking illness or injury
- Running personal businesses during work hours
- Engaging in dishonest activities while on leave
In these cases, employers must take action.
When Should You Investigate Absenteeism?
Not every sick day requires an investigation — but certain red flags should prompt further scrutiny:
- Frequent short-term absences with vague reasons
- Patterns that match weekends or public holidays
- Suspicious medical certificates
- Social media activity contradicts sick claims
- Tip-offs from colleagues
- Long-term absences with no clear diagnosis
When you suspect dishonesty, an independent investigation protects your legal standing and business integrity.
How Corporate Investigations Can Help
We work with HR teams, business owners, and legal advisors to discreetly investigate employee absenteeism. Our services include:
1. Covert Surveillance
We monitor employee activity to determine whether their behaviour matches their claimed condition.
Examples include:
- Physically active individuals claiming mobility issues
- Working another job while signed off sick
- Running a business during work hours
- Surveillance is conducted lawfully, in line with UK privacy laws and the Regulation of Investigatory Powers Act (RIPA).
2. Background Checks
We check whether the absent employee is:
- Registered as a director of another business
- Working for a competitor
- Holding undeclared employment
- Linked to conflicts of interest
- This often reveals undeclared business activities or policy breaches.
3. Social Media and Online Monitoring
Many individuals post online while absent, unknowingly providing evidence that contradicts their claims.
We discreetly monitor:
- Public social media accounts
- Online business listings
- Forums or review activity
All findings are documented to a court-admissible standard.
4. Evidence for Disciplinary Action
We prepare detailed reports that support:
- HR disciplinary hearings
- Employment tribunals
- Civil litigation
- Insurance or benefits investigations
This ensures you have the right documentation if the case escalates.
