Only if a competing company seriously wanted to snare you, from what I saw at my plant at least. I was offered $20K sign on, 2 weeks paid vacation (for 2) anywhere in the USA, 25% raise, bridging my years of service (to retain 5 weeks vacation accrual per year) ... but I didn't take it. I had fears that the new engineering group would fail, and they did about 3 years later. It was a tough decision but I think I made the right choice.
