Okay, that’s a fair position and that essentially answers my question. I don’t really have an argument for or against what you’re saying here, I was just curious to see if there is any level of utility at which you’re okay with someone being disliked by the rest of the staff.
But seriously, how am I supposed to hire and retain anyone if the workplace is hostile? Turnover and rehiring has costs, even if it's turnover of minimum wage staff.
And as a hiring manager I don't have any particular interest either in working in an environment that is hostile towards me. Or are you saying that I have an obligation to spend the majority of my waking hours with people who suggest that I have no right to be alive; or that I belong pregnant and barefoot in the kitchen?
And if I'm not willing to accept a workplace that's hostile to me, how can I ask the people I hire to accept one that's hostile to them?
There are not grey areas about "usefulness". I don't care if you're Albert fucking Einstein, I'm not going to let you scare off the other high performers or even cleaning crew that make my business productive and livable.
