The demands on you mentally, physically as well as your time in the week are enormous.
The upper levels of management and HR are devious and inconsistent.
Expect to be overloaded with daily, weekly and yearly tasks while being expected to keep work flow going. If there are equipment breakdowns or process issues ( which happen a lot) you are responsible to deal with that on top of everything else like IT problems, people issues, lack of mechanics and bad materials or ingredients. In the end you run out of time that day which will be tacked on to the next day. As your deficit grows there is no help or understanding or the proper tools necessary to do what's expected of you. So you have to be innovative and resourceful making your own tools which takes more time out of your week and is not appreciated by the upper levels of the company. Even if you share it with others.
If they decide they want to cast blame on you for something they will go back and find something on you to create a case. Things never mentioned to you as a problem in the past will suddenly be paramount and you will be punished without warning or a chance to make changes. In my case they used that as a pretense to force me to another shift as punishment.
While the pay and benefits are pretty good, its also a trap. You become dependent on that and they know they have you. They can treat any way they desire and with a check mate attitude.
