I've worked most of my life in accounting and started a new job at a law firm (in the account department) about four years ago. While I was excited to work for a new place, it's been an awful working experience and it's only worsened with the pandemic. I am done, set to retire early, and have decided to quit.
My last step before freedom is writing my resignation letter. Any suggestions on what to include? I'm not worried about getting re-hired, but is it worth it to include my critiques of the company?
