You must volunteer for all overtime and never say no to anything or else you get on the bad side of management. If you misunderstand anything management says, it is on you and you become a target. All supervisors in this area start to turn on you and what used to be ok is not ok any more. They will seek out reasons to send you home or write you up or make you re-do things if you are a target or are on their bad side because you refuse to take on overtime or go the extra mile with a smile for any of the managers. While some people arrive chronically late, you will be written up for being late once that week.
