When good employees go bad

I am saddened and sickened by my employer today. I work for a hospital as you may know. Well today my devil of a boss, decided to fire 2 employees. I am super pissed. These people have families, and were fired on the spot. They were fired when we have other people (plural) I won't name names, but who yell at patients, make trouble with the Dr's , cause rumors , talk crap like your in middle school about others. But yet they keep their jobs! What gives. Today I hate my hospital.

I want to see what goes down, but I may consider qutting if this is the way my hospital is going to be.
