The ad is likely for over the road tractor trailer drivers and they are union. I drove tractor trailers for 15 years and while there are different responsibilities, that job is just as difficult and complex as nursing. It takes skill to handle a 70 foot long 80,000lb. vehicle without killing someone. Especially in winter, in the mountains. You are away from friends and family most of your life. You miss birthdays, weddings, graduations, holidays. The expense of living on the road is high as well. It is also one of the most dangerous occupations in the country. Blow a steer tire and life gets hairy in an instant. If the ad is for route drivers, I know a few guys that do that. It is a slave driven, high stress job. And one little mishap and you are gone. Some of those guys make 200+ stops a day, in a non-air conditioned truck. I wouldn't do it for $ 100,000.
