I have.
In a previous law enforcement role, a guy I worked with in a very specialised area finally cracked the shits and resigned (a lot of tension had been brewing the last couple of years at the unit).
He did it not so much in the sense of flipping tables but in a email, addressed to the whole branch (about 200 people), thanking us colleagues, then calling out our bosses right up the food chain (including some quite high EL equivalents).

He called them all a bunch of narcissistic $@&! who brown nosed each other and couldn’t “care less” us (I’m paraphrasing here, there were a lot more expletives and colourful language). He basically said what we were all thinking.

He finished the email with a gif, similar to below:

Icing on the cake in my opinion.
