Can’t Quit On A Quitter

(I am one of three assistant directors in an office overseeing about 20 staff with one lead director overseeing us. We have a very high turnover rate as a result of the company being notorious for how poorly they treat their employees at all levels. I’ve been looking for a new job since almost immediately after starting there. I go to an interview right after work one day and am hired on the spot. I feel bad about leaving my boss without notice but don’t want to pass up the opportunity. I call my lead director to let her know.)

Me: “Hey [Boss], I wanted to let you know I was offered another job that starts Monday so today was my last day.”

Boss: “That’s great! I’m glad you found something! You’re gonna have to e-mail the corporate office, though. I quit two hours ago.”
