+Quit Your Job in StyleHis advice is more more polished and professional and worth a review (edited down, below) before too many people decide they want to be working class heroes too:
1. Make clear the decision is about you, not everyone else. This is your choice, justifiable and dead-right as it may be. Take responsibility for it.
2. Emphasize continuity. If you can retain a working relationship with your employer (freelancing, consulting, etc.), by all means do. Make your desire for that clear when you give your notice.
3. Acknowledge how others will be affected. At the very least, your departure will mean a temporary increase in work for other people, and it might mean much more. Talking about it openly makes people less likely to stew.
4. Write about it. Life-changing decisions need to be expressed in more deliberate and thoughtful ways than resignation letters and even heartfelt discussions with coworkers permit.
