A startup company is a different beast from a well established organization that has time to kill on moderating interpersonal matters that really should be left to the two private individuals to work out on their own.

If I have an employee whose skin is so graphene thin that being called a MILF is something worthy of getting management involved, forcing the startup company to engage a lawyer in an expensive legal dilemma, well that is a huge waste of company time and resources and is an indication of misplaced priorities. Perhaps this person should find employment at a large established company with an HR department who can be the referee.
