All this bull about Alaska hire, what a joke, always has been, always will be, just that, a joke.. Fly up to Anchorage from Seattle, Portland, or Minnesota and all you will  see, are dozens of Oil Field "hands" coming up to work on the North slope. Contract companies ( ch2) allow their workers to work up to 6 weeks.... so they can afford the R/T flights to get to Alaska.
This practice has allowed these companies to keep "good" employees, for years, however it promotes Nepotism, ( the practice among those with power or influence of favoring relatives or friends, especially by giving them jobs)  as a father will get his son  and then his son's son a job with the company. Hence generation of non residents now have come up and been "given" good paying jobs.
I will ask you, when is the last time, or better yet, have you ever seen an oil field company post a Kitchen, housekeeper, roustabout, or an apprentice job in our local newspapers or online? seldom at best.
