I think I would think about this...you say there may be downsizing at your current job and the other 2 make 'jealous' disparaging comments about you. You could very well find yourself being 'downsized' right out of a job. You need to look out for what is best for you and your family. 1) Your former supervisor (whom thinks highly of you) is at at the office you are applying to. 2)It has the same pay. Unless the hours are considerably worse or the office is considerably farther away, you are probably making a wise choice. Look out for yourself!
