I was blacklisted by a former manager several years ago who I had a falling out over being written up over an incident despite having followed our company's policy and procedure. I had already had my resignation letter ready to turn in because the organization was basically going to hell in a handbasket and I pulled it out and handed it to him/her and said: "Here is my two week notice. I'm leaving". A week after I left both my secretary and person doing my data entry were fired, which convinced me if I hadn't left when I did, I would have been fired, too. The company was in deep trouble financially and was looking for any
reason they could, to trim their payrolls. Anyway, I applied for a job several years ago online with a similar company and received an immediate callback. I was talking to the HR Rep, when the name of my former manager somehow came up and she got all excited and told me he/she was working for them. She scheduled an interview---only to call me back minutes later with the following terse statement: "The position has been filled".
I wanted to tell her: "Sure it has, Honey. And I'm the Easter Bunny".
