Thefts in the workplace, like most thefts, are crimes of opportunity. Whether the items taken are relatively inexpensive or more valuable, stealing is stealing.
If someone is thinking about stealing they generally will not go to the trouble to break open a locked drawer or overhead compartment in a workplace setting because they are more likely to be caught. Taking just a moment to ensure items and confidential/sensitive documents are locked up when you are away from your desk for a short or long period of time can go a long way in preventing theft.
In the event you discover items missing, please don’t delay reporting or decide the items aren’t valuable enough to bother reporting.
Thanks for your help to keep our workplace secure.
