Private Investigators Conduct Sick Leave Investigation for Employer
At Private Investigators, we assist businesses across the United Kingdom with professional sick leave investigations when concerns arise regarding employee absence. This case study explains how our investigators helped an employer gather Evidence to a Court Standard relating to suspected abuse of sick leave.
The Employer’s Concerns
A business owner contacted Private Investigators after becoming concerned about an employee who had been absent from work for several weeks due to reported medical issues.
The employer became suspicious after receiving information suggesting the employee may have been carrying out physical work while signed off sick.
The concerns included:
- Repeated long-term absences
- Social media activity inconsistent with reported illness
- Witness reports of physical activity
- Concerns regarding fraudulent sick leave claims
- Disruption to business operations and staffing
The employer required factual evidence to establish whether the employee’s activities were consistent with the reported absence.
Our Investigation Strategy
Following a confidential consultation, our investigators created a tailored surveillance plan designed to monitor the employee’s activities lawfully and discreetly.
Surveillance Investigation
Our investigators conducted:
- Covert surveillance
- Time-stamped video evidence gathering
- Photographic evidence collection
- Activity monitoring
- Vehicle movement observations
- Detailed investigator reporting
The investigation focused on documenting the subject’s daily activities over several days.
What Our Investigators Discovered
During the investigation, Private Investigators observed the employee carrying out physically demanding activities inconsistent with the medical condition reported to the employer.
Investigators documented:
- Manual lifting and loading activities
- Attendance at a secondary workplace
- Driving long distances
- Repeated physical tasks over extended periods
The evidence was captured through professionally recorded surveillance footage and detailed investigator logs.
All material was preserved as Evidence to a Court Standard.
The Outcome for the Client
The employer used the investigation findings to support internal disciplinary procedures and seek legal advice regarding the matter.
The professionally documented evidence provided the employer with clear factual information to assist decision-making and protect the business from ongoing financial loss.
