“Truckers also get abused by their employers who demand that they obey speed limits while giving them delivery deadlines that require both speeding and skipping breaks...”
You are 100 percent correct. This is the problem.
Darn near every 18 wheeler on the road has an employment ad painted on the back of the trailer.
That pretty much tells you about the turnover rate.
I don’t think there’s another job with that level of turnover.
