I don't mind travelling, but it is nice to get home on weekends. There's nothing wrong with wanting security. I had another successful career before getting into archaeology, and am now going back into. Not because of the work, but because of the puppeteering by many companies, the lies, the greed. There are very few standards and ethics as far as field techs go.
Some companies do try to keep situations fairly above board.
But, there are those others. You drive 600 miles one way, no mileage, no travel time, no job possibly when you get there. Even though you may have years as a field tech. I'm willing to prove myself. I can do the job.
