You're a Listener and you don't get it... 

Two things going on here. The radio station switchboard operator wields tons of power and can easily make life miserable.... or end it... for some radio station employees. If an Account Exec (Sales) pisses her off, guess what? Clients don't get put through, calls misdirected, phone messages deleted or lost. Combine this power with a low IQ or lack of common sense and everyday will be a telephonic adventure.

The other thing is that often radio stations will "put out the word" that they are looking to replace a jock in a very subtle, quiet way...if the guy that is being replaced finds out about it while he is still employed, things can go terribly wrong. This is why jocks who are being replaced usually don't have a clue until the axe falls after their air-shift on Friday.
