Work could be easy, but they make it stressful, I would blame on that the management. There is such a thing favoritism. If you are on top of his list then you be ok, but if you on the bottom of his list (which I would say his hate list, why is a hate list? because you would not be welcomed to ask any question) then you are going to suffer, you be on hook 24 hours no matter what. In my case I am great at my work performance. It is just his personal dislikes effecting work.
