The work locations in Nevada vary from North Las Vegas to the Nevada National Security Site 60 miles outside Las Vegas. I worked primarily at the site but lived in Las Vegas, with a 1-1.5 hour commute each way. Also, I worked 4 days a week, 10 hours a day and if you add the commute thats a good amount of time away from family but the compensation and co-workers made it bearable.
I learned how to be a professional and how to work with people of differing personalities and view points.
I'd have to say my only complaint was the varying levels of management and how when budgets seemed to get tight and there was talk of layoffs or furloughs for workers on the ground, there always seemed to be new management positions opening up and being filled.
My co-workers varied in disciplines and fields but in general they were some of the best people I've ever met.
The hardest part of the job was working in the elements which in the desert meant dealing with extreme heat in the summer. Staying hydrated and maintaining safety while also being productive was a constant struggle.
What I enjoyed most about the job was the group success and the comradery it fostered. When we all did well at a job location or on a project it made for a less stressful/dramatic work environment and people enjoyed coming to work.
distance from major city, loose work hours of those in town vs. the strict work hours of those at the site
