Kindergarten nannies generally don't have the talent for teaching people how to not be jerks - they just put the jerks in timeout. Some eventually grow out of it. Some eventually get medication and/or therapy that addresses the issue. Some eventually respond to a lack of environmental stressors when they move out of their parents' house. And some simply stay that way. If you've hired someone in the latter category, yes, delivering business value requires you to deal with it. Firing them is an option, if that's really net positive for business value; sometimes it isn't. Seeing if you have the knack for teaching them is another, and likely highly profitable if you can do it. Handing down rigid rules is yet another option - not great, but quick and usually effective.
