I hate, hate, HATED conference calls. They were necessary for the dumber end of the spectrum, I suppose. Everyone else could read emails and survive. The absolute WORST was when I was working at the shop at the airport- fully HALF of the stores in the dm's district (five) were in the Atlanta airport, the dm was from Atlanta and he was in town most of the time which meant he was in our stores all the time, and we had a regional manager who was ostensibly in charge of the Atlanta stores as well. So I had TWO BOSSES that I saw all the freaking time (and liked to give orders that would countermand each other), was in constant email contact with them AND had their cell phone numbers yet we had to have at least 2 conference calls a week.
Shit like this is why I can't work retail anymore. I'm getting insane just THINKING about it.
