I am close to a job offer, and want to know that if offered a salary at this time, should I still negotiate? Normally I would, but considering the need for work at this time, would I look ungrateful or greedy? Also, note that I am laid off so I do not want to lose any chances here, but at the same time when all this washes over I don't want to be stuck in a salary I knew I should have negotiated.
