I would take a non-aviation job before working at an alter-ego. Seniority is not moving in this industry, your career will progress the same whether you are the lasy guy hired in the last upswing or the first guy hired in the next upswing.
After having done it once, I seriously doubt that I would work for a bottom-feeder again either. There are easier ways to make $20K and be gone 26 days/month. Alaska north slope, etc.
