Rigoletto...
Wow, you're quite the arrogant little stiff. Tell me, do you occasionally see yourself looking at the undersides of Boeing 747's whilst looking down your nose?
No matter what the company policy may be, they had established a very lax precedent - Nobody honestly cared about people having speakers, headphones, etc. There is nothing preventing me from doing my job just because I have music playing very softly in the background. In fact, many of the computers have built in speakers and the audio drivers are installed. So listening to music has nothing to do with it. The real issue is they decided out of nowhere, without warning, to act on a seldom observed policy.
And as for my letter, it doesn't need to be very formal. All I want is my speakers back, I'm not trying to sue them. This is dealing with my manager, who I'm on a very casual first-name basis with, & the head of IT who's not even on site.
Next time you want to flame me, why don't you learn something about me?
