Tnt and Mike,
Those are excellent points. TNT, I understand what you were trying to do. When I came here, I already had a pretty good idea where I was going. I will speak to the Kelly folks about posting a response, so they can clear up some confusion.
SEC does control the assignments on the reservation. Its very much like any other company. If you knew Joe Worley, you got a good job with DNI, CE, PSESI, etc. If you knew John Ellison, you got a good job with Numanco. If you knew Bruce, you got a good job with Bartlett. And so on and so on.
This industry was founded on the GOBN (Good Ole Boy Network). If you are on the inside, you win. If you are on the outside, you hope for a good assignment, until you can join the GOBN. Like it or not, this is what we work in. We have all created this monster and are all still sucked into it, until we can move on.
Merlin, as it was posted earlier, get all the info you can before you sign the proverbial dotted line. Take the posts to heart when considering your next jobsite, and make a educated decision for your career.
