This is one of those horrible bosses that deserve to go to jail. Not only was he watching his employees in the bathroom, but he was overstepping every single boundary of his employees.
When you go into the bathroom, you go in there not only to use the toilet but to have privacy. You don’t expect a hidden camera in the bathroom. They could seriously get their boss in trouble if they wanted to. It’s illegal on so many levels. We wouldn’t just quit, we’d call the cops and let them know what happened. If he isn’t caught now, who knows if he’ll stop (via Food Is In The House).
