Nevermind posting it on the internet, indexed or not.

I did this many times, usually on the verge of a burnout. Almost every time, except for the final one, it helped me identify the pain points as well as the highlights, find ways to fix the underlying issues then get back to speed and regain satisfaction from work. I think it's a great way to gather more insight about yourself and your workplace. Try drafting one now especially if you do not intend to leave :)

> Yeah, I can't recall ever drafting and saving/keeping a resignation letter from a job (volunteer or otherwise) that I didn't intend to leave...

Writing letters that you don't send is an effective, practical, recommended way to manage anger and other emotions. It's even better than posting angry rants on the Internet. :)

I worked at a tech company where the management decided to move the offices to a new office park built on top of a toxic waste dump. We all printed off our resumes and left them on the laser printer, that was the end of that
