My boss has always been a mean jerk.
He would wait until I was leaving for lunch & bring me "rush" letters to be typed.
Or he would wait until the last minute to approve time off. Often, at the last minute, he would deny it.
I knew he had serious control issues, and a bit high strung.
Anyway, he had been working on a big project for the district manager. We had a glitch one day when the computers went down.
Just as they came back online. I went in & wiped out his project.
He was so pissed! But, we blamed it on the glitch.
He wound up getting fired, but I don't feel bad. Maybe at his next job, he won't be so mean!!
