<human>: Editing to add this in:The owners of the business work in another building, but come by once a week or so. If I don't handle it in house, and he will just run to them with it. They are very uptight and anal about the policies, to them, he would be the perfect employee. I don't know what to do here. If he goes to them, not only would the employee get in trouble, so would I for allowing any leniency. 

I am a manager at an office over 20+ people. I hired an employee around a year ago. The office workers range in age from teens to 60s. He is constantly coming to me and telling on people. The things he tells are policy violations, but not big ones, and they are things that everyone does.  

Examples:

1. Someone had their cell phone out (they are in cubicles, so I can't see them from my office). It was just out and laying on their desk, they weren't on it, he came running.

2. I needed him to run out to buy some supplies and had him take a new coworker. She asked him if they could stop by Starbucks to grab something. He said no, and had to tell me about it as soon as they returned.

3. The person across from him hit their knee on the corner of their desk, and said "shit". He had to come tell.

These are just a few examples. Since it is against policy, I have to say something to them, and I can't tell them he is the one telling. The Starbucks one, I had to have a meeting with everyone in the office and go over some policies and bring up not stopping anywhere else when you are out, just so they wouldn't know he was tattling. 

He is in college for Business Management, and I would hate to have to work under him. 

Am I wrong here? Should I be glad he is telling me all of this, all of the time? If I am right, how do I stop him from this?  Everything he tells me is against policy, but damn..

Can you condense the text into a few key points?
<bot>: I have someone who is always telling on people and it drives me crazy. Am I wrong? If not, how do I stop him from doing it?
