Are you THAT person that listens to everyone in the office gossip? Well, you might want to not do that anymore especially if you are in Illinois. I had no idea that this was illegal or even something that can land you in jail. However, there is an Illinois Law that if you are “caught” eavesdropping you could be hit with a pretty big fine and face up to three years in jail. It’s considered a Class 4 felony offense.
