What is employee absenteeism?
Absenteeism can be described in the context of employment as an employee who regularly fails to turn up for work with little to no explanation, or for reasons you begin to believe are false. Absenteeism is different to authorised absences, such as annual leave entitlement, medical appointments, long term sickness, religious holidays, bereavement leave, and maternity and paternity leave. It even differs from irregular, unavoidable absences, such as genuine illness, or family emergencies. It’s when these irregular occurrences turn into regular ones that form a pattern that it becomes an issue. There may well be a genuine explanation, but in some cases, it may be that the employee is off work for no good reason.

We’re specialists in investigating absent employees
Illness and emergencies are unfortunate realities of life. In such situations, employees are encouraged to address them and take the necessary sick leave; nothing is more important than an individual’s well being. However, fraudulent employee absence is also a reality, and it is one that can have severe negative effects on the efficiency of an organisation due to lost work hours and the morale of colleagues. It can be highly valuable to investigate an absent employee, especially if you suspect something is amiss.
Discover fraudulent employee absences
Employees who engage in such deception have often done so for quite a while, and as a result, it can be difficult to discern whether their absences are legitimate or not. This is where skilled private investigators such as ours can be invaluable: planning a discreet and effective course of action and then executing it in order to identify illegitimate absences and nip them in the bud.
The legality of absent employee investigations
Obviously, if you’re planning to keep tabs on your employees, there are some legalities involved, and these are set out by the ICO. Their guidelines address the fine line between your organisational needs and your employee’s rights to privacy. We’d suggest reading the ICO guidelines in full if you’re looking to monitor your employees to sniff out employee absenteeism. However, in short, you’re advised to assess the potential impact of your monitoring on employees’ privacy, conduct data protection impact assessments, and maintain clear communication about monitoring practices. Data access should also be limited to authorised personnel only.
Covert monitoring
We’d also draw your attention specifically to the section on covert monitoring. In this section, the kind of monitoring you’re considering by engaging with a private investigator is covered. One of the many things to ensure is that ‘You should be satisfied that there are grounds for suspecting criminal activity (or an equivalent, such as gross misconduct) and that informing workers about the monitoring would prejudice its prevention or detection.’ It also states that if using a private investigator such as UKPI, you ‘must have a contract in place that requires them to only collect information in a way that satisfies your obligations under data protection law.’ UKPI is proud to be a member of the ICO, and we are, of course, more than happy to discuss the legalities of an employee absenteeism investigation during your consultation.
How do employee absenteeism investigations work?
Our expert absent employee investigations always begin with an initial consultation to gain an understanding of the employee you’re looking to investigate, and what kind of evidence you need us to collect. Then, with the green light from you, it’s with us to discreetly gather the evidence you need, whether that’s physical evidence such as photos or videos, or digital evidence, such as screenshots of social media activity. Following our employee absenteeism investigations, we’ll provide you with both the evidence, and a report of our findings.

Confirm your suspicions
For various reasons it is a bad idea to accuse an employee of lying about their illness or reasons for absence without proof. However, through years of experience, it is likely that when an employer’s suspicions are strong enough to warrant action, there is some foundation to them.
When we investigate an absent employee, our investigators provide both the evidence necessary to deal with an employee’s deception and protection from finding yourself in an unfavourable or actionable position.
Discreet employee investigation
Our private investigators will first talk with you about the employee’s general history to establish any patterns, and to create a plan of action. After this, our investigators will begin their inquiry acting with the utmost discretion. We understand that it is imperative that neither the employee nor any other party is aware of the investigation to preserve your relationship should the absence prove to be legitimate and to protect you from liability, legal or otherwise.


Detailed reporting by your private detective
In all cases, we will provide a full report of our findings and photographic and/or video evidence. Should a fraudulent claim by the employee be discovered, you will have the hard evidence necessary for dismissal.

How to spot sick leave fraud
It can be so hard for an employer to distinguish genuine sickness from sick leave fraud, but some of the signs to keep an eye out for include:
- Patterns of absence, such as regular mondays or fridays (which could indicate a penchant for a long weekend), or a series of small, non-certified absences of a day or two where no ongoing illness is present
- Public posts to their social media accounts that do not marry up with illnesses the employee claims to have had
- A decline in work quality
- Repeated absence around busy periods at work
