Sentry Private Investigators offer discreet investigations services to evidence the truth behind workplace absenteeism.

What is an Employee Absenteeism Investigation?

Employee absence private investigations are a service provided by SPI to determine the reasons for an employee's extended or frequent absences from work. The private investigation may be requested by an employer who suspects that an employee is taking advantage of their sick leave, holiday time, compassionate days or engaging in other activities that prevent them from fulfilling their job responsibilities. During the investigation, SPI use a variety of techniques, including covert surveillance operations to gather evidence relating to an employee's absences.

Fabricating Absences

employee absenteeism

Most employees have genuine reasons for taking a leave of absence, but some have other ideas. It's the latter that we are concerned about, and employers should be to. Employers generally have to take an employee's word for why they are not coming into work. But, with the evidence our private investigations produce, employers can  get an understanding of what us really going on. It's like most things that don't add up, and if your gut is telling you that an employee is lying, then he or she probably is. When it's got the stage where a business has had enough of the lies and excuses. it's time to get it professionally investigated.

Business Support

SPI are a Birmingham based private detective firm with coverage across both the West Midlands and East Midlands. We provide the clear-cut evidence businesses are seeking to enable informed decision on how best to proceed with employee absence issues. If the employee in question is genuine with regards to his or her reasons for absence, then great, close the case and support the employee in the best way possible. If the employee is found to be fabricating his or her reasons for absence, then  disciplinary proceedings will be more appropriate. The evidence gathered through the course of our surveillance operations is distributed in 4K video resolution, and backed up with a detailed time-lined report complete with stills imagery. 

Moonlighting Absences

Alternative working arrangements, or 'moonlighting' as it's known is a common occurrence with employee absence cases. An employee can only be in one place at one time, and if the employee is receiving pay from one employer, he or she can earn double by working elsewhere. Business competitors also try to poach employees from other businesses. They seek trained and experienced professionals from other companies and usually offer better pay packets. This is a golden opportunity for employees, especially if they can do when taking absence days with their main employers. Furthermore, competitors often seek trade/product secrets and take no issue in sourcing this information from a competitors employees.
