I've only ever been an IC. It's interesting you assumed I was a manager. I've learned the tricks to get almost total freedom at work and wanted to share. Quid pro quo is the name of the game in business. You have to give something to get something and trust is everything.
You basically quoted word for word multiple times what a petty and vindictive manager I worked for about a year said repeatedly in almost all your posts.
Cynicism will hold you back.
