It’s absolutely maddening! When a coworker plays music too loud, if you’re anything like me you want to scream. Except THAT would be seen as a bad thing. But their loud music is ok?
Early on in my career I worked in a bank, where my cubicle was right next to someone who loved his music. The way we were positioned, I was the only one who heard Arthur’s music. Well, besides him. And he found my annoyance amusing. Not his problem, he told me.
