When I worked at Wally World 3 years ago in Wisconsin they were begging people to go to Williston. $15 per hour plus moving and housing expenses. If there is a worker shortage who will build these roads and houses and schools.
Fifteen an hour here is about what fast-food workers make. WalMart was paying $18 for night stockers and checkers.
Oilfield wages are significantly higher, include massive overtime, benefits, etc., but usually require background checks and drug testing.
