How many days are they out for?
And how many miles
Ours vary from just under 4,000 to almost 6,000 miles. The ones at 4,000 will have another leg added at some point and come up to the average which is around 4,800 in our building.
Days are hard to describe. It may only take 3.5 days to do a run but they will have you back through your home domicile for an hour to 18 hours at least once in the week so your 4 days of work takes 5 or 5.5 days to complete.
I cover a run occasionally because I like the A driver. It's about 5,200 miles and he makes about $135k a year (maybe $145k, I don't remember what he told me). To make that money he is home roughly 38 hours from late Sunday evening until Tuesday afternoon. And then is scheduled back for another 18 or so hours Wednesday into Thursday. That's a tough life.
