My direct management chain has no "leaders", just managers/bosses. Command, control, fear, dismissal. Well-protected, surrounded by "yes-men", glib in explaining everything away, and no desire to improve or even listen to suggestions on how to improve the environment.
The canned HR responses in here with "we care, we perform questionnaires" are great for show, but after all, most HR anywhere doesn't work for the employee, but for the employer.
The more you 'suck it up and shut up', the better you will do.
