re: Quitting a job?

I once gave a boss 6 months notice. I was only 1 of 3 folks in North America in my role and it really needed 4 or 5 people. So I wanted to give them ample time to hire and train my replacement. I was real worried they would let be me go sooner, but I thought it was the right thing to do. Turns out one of my colleagues gave 6 months notice the same week for the same reason, so my boss was pretty happy with the notice.

Just be honest and professional.
