 The Fight Against Employee Theft

workplace theft security measures

Businesses are desperately trying to combat theft in the workplace with some effective methods of prevention to avoid the need for workplace theft investigations. For example, CCTV in the workplace, random percentage searches etc. However, these security measures will only achieve so much. Staff should know exactly where CCTV cameras are installed in the workplace, as it is a requirement under employment law when monitoring employees. Percentage searches are only affective if the thief is actually searched.

SPI deploy undercover surveillance operatives into the workplace to actually witness and evidence the thefts taking place. We operate with discreet, covert cameras to capture the thief's every movement.

Three Types of Employee Thief

The Lazy Thief

The lazy thief is more of an opportunist thief. He or she will take items of high or low value if it is deemed low risk, and without much thought. This thief is likely to be less experienced but will jump at the chance if the opportunity arises. If there are few security measures in place, this is where the lazy thief will be operating. The lazy thief will also make plenty of mistakes along the way, making it easier for him or her to be caught should it be investigated. 

The Greedy Thief

If it's shiny, the greedy thief will take it. Although more experienced than the lazy thief, the sheer greediness will be the demise of this thief. One he or she has gotten away with it a few times, the greedy thief won't be able to help him or herself when opportunities arises again. Even with security measures in place, the greedy thief will just carry on. The greedy thief, being more experienced will make fewer mistakes, but will trip up somewhere along the line.

The Professional Thief

The professional thief is the most experienced of them all. This thief will assess the security measures and weigh up the risk worth reward. This one may even conduct some form of reconnaissance and have a planned route for handling the stolen goods. The professional thief will make very few mistakes, making him or her somewhat difficult to catch out.

Undercover Employee Theft Investigations 

Certain employee theft investigations involve the embedment of undercover surveillance operatives into the workplace. This to effectively provide the clear evidence of who is committing theft, and on what scale. Employee theft investigations don't just stop there though. The operation may lead to management wanting to know what is actually happening with business stock levels. We continue with the investigation and deploy mobile surveillance operatives to evidence where it is going. Our highly trained covert operatives will be in the thick of the investigation. They discreetly compile irrefutable evidence to place the business owner in an empowered position to take action against employees suspected of theft.
