I win!
Work/trainee update: Today she didn't show up at all. At the end of my shift my supervisor said that she'd "resigned". Ha! If she gave me anymore attitude she wouldn't have had to worry about resigning. Well, at least it saved me from having to tattle on her to the sups about being so awful on the phones. One of co-workers actually came up to me when he saw that she wasn't there today and said that he'd overheard us a couple of times and had wondered how she'd even made it through training without getting fired *LOL* At least now I know it's not just me who thought she sucked. (Is it wrong of me to be happy that she left?)
