I lasted thirty-five years in that job. That boss got fired in a year. You see, I complied with the absolute letter of the rules. Nothing could be done to discipline me, especially with forty-nine other witnesses to an upper-level manager admitting that the production targets were knowingly unrealistic. One of my problems with you is why did you want to stay in a job where you were being taken advantage of? Are you a masochist?
Actually, I eventually quit (but the next job was even worse, so be careful what you wish for.) I could have left that job a year earlier, but the Drinking Buddy had a death in the family that took him off line for a month, and quitting then would have been a really jerk move on my part.
Oh, I honestly doubt that if they fired you, 49 people wouldn't have done anything other than loot your cubicle for supplies.
