Sexual harassment training, religious accommodation, equal employment opportunities. These are legal terms that when proven to be violated are guaranteed million dollar lawsuits in favor of a complainant and ensures losses for a company.
The laws to protect actual worker rights as opposed to those individual rights are worlds apart. There seems to be no piece of HR that deals with theft of wages, denial of sick leave, hazardous work conditions and comparing wage and salary compensations. It is specifically designed to prevent lawsuits and loss of capital.
The grift is nearly perfect too because Human Resources sounds friendly, compassionate and reasonable.
Try going in there for being worked overtime or not getting paid on time. Good luck with that. I'm a human God dammit! This is human resources!
