Leaving a Job

A couple years back I decided to leave the company I had worked at for 8 years to get a 40%+ raise. The letter I wrote was short and generally nice. I had no need to burn bridges and I was happy to work there — but a 40% pay difference is hard to pass up. (I ended up staying when I got a matching offer but only after I sent in my letter.) I hope I never have to leave a job on bad terms, but if I do I hope my resignation letter has to be published in the company’s public files.
