No, I'm dead serious. I was at a warehouse that went through janitorial staff every month (this was more to do with us being a very second-third-27th chance employer, but in K's case also... not hostility but sexual aggressiveness from many workers) I know what turnover does to over all moral and productivity and I would take good janitors over a raise any year.
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?
