Approximately 80% of employees steal either time, money or product.
A prominent Newport Beach attorney representing a large beer manufacturer contacted us. We met with the attorney and the company executives at their corporate headquarters.
The company had a problem: large amounts of inventory were simply missing. They had a certain amount of product on hand, but their internal accounting told them they should have more money.
Our private investigators provided employee surveillance, and later, in-depth interviews and interrogations of employees.
We quickly discovered a number of employees were smuggling product out of the factory. The results from this investigation were handed to the District Attorney. As a result of our investigation, 17 people were arrested, prosecuted and served jail time.
A Human Resources Director called us at the direction of the Chairman of the Board and informed us that the President was known to be having an affair with a subordinate. Notwithstanding the fact that the executive was married, company policy expressly prohibited such office relationships. The clients also determined that there was a significant risk of legal action by the female against the company and the executive if and when the relationship eventually became public.
Although the affair was routinely known and discussed within the company, the Chairman had no hard evidence to support termination of the employees for violating company policy.
We were engaged to operate a ten-day surveillance, which soon caught both subjects in compromising positions and places on videotape.
After presenting our findings to the corporate board, we discussed strategic options to resolve the situation. Our goal? To minimize the risk of a lawsuit from either party. The board agreed that we should manage the termination process for both employees in a discreet and confidential manner using the video evidence as justification. This enabled the client’s Human Resources department to maintain a level of separation from the process to minimize legal risk while effectively bringing the situation to a close.
The struggling economy has created yet one more problem for business owners: skyrocketing employee theft.
