Don't plan on having a moment to sit down if you are in a production roll. Even when machinery is not working, and there is nothing else to do, don't sit. And when/if your lead tells you to not sit, and your coworkers are sitting, they are allowed to sit apparently. Leads act like children and play favorites. The design of the place is stupid. You would think that all parts would move on a conveyor in a 1,2,3 flow process. That isn't so, carts of parts need to be walked from one end to another.
Hours, process, coworkers
