Every morning, the AM sort manager sets up her speaker and blasts music at nightclub volume during the entire sort. I'm about 100 feet away from the speaker and I have to raise my voice and regularly ask the guy next to me to repeat himself in order to communicate. If you actually walk down to the cans where the speaker is sitting, it's absolutely earsplitting. I feel so bad for the poor handlers who have been up since 4 AM and have to be subjected to that. All of the music is from her personal, esoteric playlist and no one appears to actually be enjoying it. She shuts it off whenever there's a higher up at the station, so I imagine it's against policy and it's really grating on my nerves. My question is what can I/should I do about it? I don't like to go over people's heads without talking to them first, but she's very unapproachable and prone to yelling. Any suggestions would be helpful.
