That is all.
I would rather not burn bridges - you never know if you may want to work at a company where a previous co-worker is employed at. Leaving with grace is always better then leaving with attitude.
Indeed. This is certainly a case where honesty is NOT the best policy. Because I generally leave on good terms I've been offered consulting gigs with old employers and I get good recommendations. I also have been offered full time employment by former employers and former co-workers.
