This question already has an answer here:
I work for a government agency in a consolidated services unit. There is always work to do, but a lot of people seem to have time to socialize all day long. Two things irk me. 1. People who hang over your cubicle wall and watch you work behind your back. Not just your supervisor. 2. A co-worker who is in the cubicle in front of mine has a habit of looking into my cubicle and staring at me or my screen. I sit sideways to the entry of my cubicle, so he has to crane his neck to see what I am doing. I do purchasing, so I have a lot of sites open for business. I am allowed to listen to streamed radio programs, playlists, etc. No videos.
I've tried the turn and look at him, turning my back. But this just disrupts my workflow. I tried to ask him about it, and he just waved me off. Now he comes into the workspace singing off tune and tapping on his desk for 15 minutes.
