The only way that you will succeed here (or anywhere) is having a willingness to work hard. It is not unacceptable to be asked to do different things in this job to be asked to work overtime or even to be sent home early (all in which is covered in the orientation). Everyday is different and management has to do the best they can to make the best decision possible.
If you aren't willing to work hard and do what you are asked then I would assume you would have a hard time anywhere you work. I've worked here for 10 years, worked in all departments and on both shifts. There are good days and bad days of coarse but keep your head up, work hard and you will succeed here for sure.
