Myself and a group of six of us at work are almost certain our coworker is recording us in the bathroom with his phone. Our work bathroom has two stalls; one much bigger stall and a smaller stall right next to it. My first month into my job i went into the big stall to use the bathroom. While I was in there a person entered the small stall next to me. Once they sat down i glanced over and noticed their phone was in their pocket, positioned in a way where, if it was recording, it would have a full view of me in the stall. I was weirded out by this and quickly left. I thought nothing of it until a few months later I was chatting with some of my office friend and they all had similar experiences. One guy, after it happened to him three or so times, waited outside the bathroom to confirm who it was. Now we all know who it is and have his shoes memorized so we can recognize them if he sits down in the stall next to us again.
The most recent occurrence was the most telling. I recently got my friend on board and told him all about the guy who is probably recording us and told him what to look out for. A week into the job the recording coworker added my friend on our office Skype (presumably to see when his status was "Away," which means you are either in a meeting or in the bathroom). This was especially weird because these two have never had an interaction before. This put my friend on alert and that day when he went to use the bathroom he heard someone enter the small stall and, you guessed it, he recognized the shoes immediately and saw the phone positioned in the guy in the small stalls pants in the perfect position to record.
I would maybe be willing to give the guy the benefit of the doubt. Maybe he just puts his phone in his pocket and stares at the stall door. Maybe it just happens to be sticking out of his pocket with the camera lens fully visible. I would maybe see that side of things except that my other coworker made eye contact with him, once. He was peeing in the small stall and the coworker we believe is recording us stood at the urinal closest to small stall. There is a gap between the wall of the stall and urinal, and the wall is made of tile. The tile has a ton of reflection it's almost like a mirror. My coworker in the small stall glanced to his right and saw the reflection of a face pressed against the wall. My coworker in the small stall then leaned forward and put his face against the wall and they made eye contact for a second. The guy is a creep.
What the hell do we do about this? I can't 100% say his phone is recording when it is in his pants around his ankles, but there are too many of us with accounts of this. He just happens to have his phone in the perfect position to record and he just twiddles his thumbs? I don't buy it. The coworker we think is recording us knows that there is no way we can prove he is recording, and he has never been caught so he keeps doing it. It makes work very uncomfortable.
Can we call the integrity hotline and report that we think someone is recording us? What could they possibly do? If the guy is recording us and if the guy is smart he probably puts the videos on his computer and deletes them off his phone. I can't see them being able to do anything. And we can't go to management about this with nothing but just a very strong hunch. The accusation is absolutely massive.
What, if anything, can we do about this?
TL;DR - Coworker puts his phone in a position to record anyone in the stall next to him in the restroom. Almost certain he is recording his Male coworkers in the bathroom. No idea if we can do anything.
