Sick Leave, Side Hustles and Workplace Fraud: When Employers Need Answers

Flexible working and the growth of side hustles have made secondary income far more common in today’s workforce. Many employees legitimately supplement their income through freelance work, small businesses, or online ventures outside their primary employment.

Recent HR commentary has also highlighted the growing challenge for employers in distinguishing between legitimate secondary work and potential misconduct. As explored in this article on moonlighting and workplace misconduct, the key issue is often not the side hustle itself, but whether the activity conflicts with the employee’s obligations or stated incapacity.

However, concerns arise when an employee who is signed off sick from their main role appears to be generating income elsewhere.

For employers and the solicitors who advise them, this can raise serious questions about honesty, trust, and potential workplace fraud. In particular, cases involving employee working while signed off sick or undeclared secondary employment may indicate misconduct or employee sickness fraud.

For professional investigators, these situations often require a employee sickness fraud investigation to establish the facts and determine whether the employee’s activities are consistent with the reason for their absence.

When Sick Leave and Secondary Income Overlap

In many situations, having a second source of income is not the issue. Employees may operate small businesses, work freelance, or earn money online in their spare time.

The concern arises when someone is receiving sick pay or is absent from work due to employee sickness, while appearing capable of working elsewhere.

Cases involving working while signed off sick can raise questions about whether the employee’s absence is genuine, or whether the situation involves misrepresentation or abuse of sick leave.

From an investigative standpoint, these cases are rarely straightforward and require careful evidence gathering before conclusions can be drawn.

At Taylor Investigations, we frequently encounter situations such as:

·      Employees claiming long-term sick pay while undertaking work elsewhere.

·      Individuals carrying out physically demanding work while signed off with related injuries.

·      Staff operating businesses or secondary employment during periods of sickness absence.

·      Evidence suggesting an employee is capable of activities they claim they are medically unable to perform.

In these circumstances, concerns often shift from simple policy breaches to potential employee sickness fraud or workplace misconduct.

The Role of Surveillance in Long-Term Sickness Investigations

When concerns arise regarding employee working while signed off sick, employers often require clear and objective evidence before taking any further action.

This is where professional investigations and surveillance can play a crucial role.

Discreet surveillance in long-term employee sickness investigations may reveal:

·      Whether an employee is undertaking paid work elsewhere.

·      The physical activities being carried out while signed off sick.

·      Behaviour that contradicts the reported medical condition.

·      Evidence of undeclared employment or business activity.

The purpose of surveillance is not to make assumptions, but to document factual evidence. This allows organisations and their legal advisors to understand what is genuinely taking place.

Why Evidence Matters in Employee Sickness Fraud Investigations

Acting on suspicion alone can expose employers to unnecessary risk. Allegations involving employee sickness fraud or working while signed off sick must always be supported by credible evidence.

Professional investigations rely on lawful surveillance, intelligence gathering, and detailed reporting to establish the facts.

In some cases, investigations confirm that an employee is abusing sick leave or undertaking undeclared work elsewhere. In others, the evidence demonstrates that the activity observed is consistent with the employee’s circumstances.

Either way, the organisation gains clarity based on evidence rather than speculation.

Long-term sickness absence can have a significant financial impact on businesses, particularly where sick pay, insurance benefits, or ongoing operational disruption are involved.
