In addition to Shayne's suggestions, which are right on target, I would add that the next logical step from laborer is to try to get a job as a deconner. No matter where you end up, the experience you gain doing decon work will serve you well. It is a 'technical laborer' position. I know I will get some grief for saying that but here is the reasoning: As a laborer you will be doing whatever it is that needs to get done and does not require any specific qualifications. As a deconner you will still do a lot of work that is similar to what laborers do, but you will also be trained to do work that involves specific skills and acquire valuable technical knowledge in the process. Some decon technicians move on to be HP techs after acquiring the experience necessary, some remain as deconners throughout their career. Any HP will tell you that a good crew of deconners is worth its collective weight in gold.
Even if you don't become a career deconner or move into the HP ranks, the experience of being a deconner will be invaluable. Operators, chemistry techs, I&C techs, mechanics, and even planners that understand the things you learn as a deconner will do their job better and gain a better understanding of what it takes to make a power plant function. And as a deconner, you will get to see a lot of those folks doing their job (well, probably not the planners) and can get a better idea of what it is you might want to do.
One last thing -- keep your eyes and ears open, ask questions, prove you are not afraid to work and show an interest in doing your job right (OK, that is more than one thing). And do your best not to get stuck in the same job over and over. The Turbine is not a bad place to get started, but if you are working in a PWR, try to get a job in the auxiliary building or contaiment next... there is much more to be learned in those places if you plan on sticking to nuclear. If you are in a BWR, try to get in the reactor building or drywell -- roughly the equivalent to the PWR aux building and containment.
The fact that you care enough to ask bodes well for your future. Good luck to you.
