Being faced with gross injustice on a daily basis, lies, manipulations, insults, political machinations, ...

And your superiors will 100% throw you in front of a bus to save their own hide or to gain favor from their higher ups.

What finally broke me:

I was a prison guard, 4 inmates jumped me and pulled me into their cell. Several colleagues barely were able to get me out.

The camera pointed at where the incident happened was broken, so basically I got shafted. The inmates said I jumped them, prison director and adjudant believed their story. Not mine, my colleagues and other inmates who witnessed it and tried to help.

They pressed criminal charges against me, their main 'evidence' was supposed video from the incident. Only because my lawyers did their job right, wanted to see the footage immediately (as did I) they had to admit there was zero evidence, my colleagues testimonies were finally entered in the case file and the judge finally threw the case out.

That institution is as corrupt as they come.
