what happens say if you switch jobs? do you transfer the 401k? take it out? know of any good websites explaining this?
it all depends. usually you can transfer it to your new job. but, if your company matches some amount that you invest into it, you may not get 100% of the money they put into it unless you're fully vested, or other rules the particular company has in place.
ask your HR dept about it.
heh and im going to assume that my boss is evil enough to release me as soon as that 'fully vested' period is about to happen, gotta love it
