Ask HN: Just Sack Me

As a very conscientious worker I think I have learned an important life lesson over the last 30 years of work. A coping mechanism which says, "just sack me". This translates as I am doing the best I can. That I have realised others will take advantage of my good will. As others sit around and twiddle their thumbs I will be given more work.

My question is can anyone frame "just sack me" in a better way? I imagine I am expressing something important in not a very articulate way. In a way which sounds like stick it to the man. I would like to help others who are struggling in their work with what I have learned without sounding so negative.
