A boss will teach you what to do. A leader will show you how and why to do it. Something the company knows nothing about. My manager was a joke and was friendly to your face but when no one else was watching ... the worst person I have ever worked for. Ripped me apart cursing and yelling at me with my 3 year old son in the background on Skype it was so bad my son started to cry. No one deserves to be looked down on or talked to that way.
