Someone has been stealing things from everyone's desks in our office. I setup a teddy cam on someone's desk (with their permission) to find out who was doing it. Turns out it's the owner of the company.
Since a lot of people are asking. I confronted him about it in private. Over the course of 2-3 months the majority of things started reappearing and the stealing came to a stop after that. At least for the most part, occasionally something would go missing but it wasn't near as often.
