Management is horrible, a bunch of people in charge who have no clue of what they are doing. Supervisors don't help, can't help, won't help. Literally will walk-off from a person when asked a question, or just tell them "No", I won't help.
HR is even worse! No, help from human resources. They will tell you, that's your supervisors' responsibility. Well, your supervisor said, this...So whatever your supervisor or manager says happened, it happened as far as HR is concerned.
