Utility/City vs Contractor/Albat

Need your guys advice on the situation I'm in. I'm currently ranked #2 for substation thru ALBAT waiting to get called out to work. Yesterday I just got an offer of employment for a city job with Chicago CTA as a lineworker. Based on your experiences and others what do you think is the right move? I wouldn't want to get laid off working with albat and with a contractor cause I got a mortgage and bills to pay. But I also want to be set up good for once I top out. Let me know
