Human resources exists to make sure and treat its Human element, the workers of the company that do the REAL work, as a disposable resource. they are class traitors, Nazis and the enemy. Never talk to them unless absolutely forced to, because keep in mind they often find a way to rid the company of an offender AND an offendee.
Never trust an HR member, never invite them to company outings. If they wanted friends, they shouldn't have become class traitors.
