I'm going to raise legitimate concerns towards management and get shifts cut as punishment
Why do you want to talk about concerns with the shifts?
I do not want to work with a manager who is being so unreasonable with me
It's okay to have an open line of communication with your manager, but don't do so at the expense of your job or anyone else's. Try to be reasonable and come to a compromise if you feel your manager is not working well with you.
He's the unreasonable one, he needs to learn how things are around here.
Well if you feel he is being unreasonable than it is probably a good idea to talk about why you feel he is. It is great to be open with your feelings when it comes to things like these.
