HR, managers, supervisors suck, literally. HR is incompetent as so are the corupt managers. Due to company size most of the supervisors there are perverts and get away with with sexual harassment which is the norm. Investigations are usually dismissed within time with no type of justice which is why sexual harassment won't stop.
Also, a lot of favoritism in play. If you're not a favorite expect to be over worked or frown upon by supervisors.
