Nobody is hired for a job if the person hiring thinks that the employee will murder them. So I guess that makes the most salient job description "refraining from murdering your boss"?

Or it might be that any baseline expectation which applies to 99.99% of all employment (I don't need Kevorkian giving me the side eye..) fails to be a good way to differentiate one kind of employment from the next or describing how and why people choose a specific kind of employment
