The trick is knowing how to phrase it so it's clear it's a problem for the company. They usually love SBIN (situation behavior impact next steps) so it's good format to use:

Dear HR,

On the meeting XYZ

My boss Bully McIdiot was screaming like a toddler at everyone that disagreed with him

This is preventing the free flow of ideas and Innovation and creating an »»hostile work environment««

So he should be fired. Preferably from a cannon.

kisses and hugs,

the employee of the year
