The never ending debate. How long to sit and what is cheap. Perhaps somewhat easier to answer with a flat rate carrier than a percentage carrier. It happens various ways but often it works something like this.
A load is offered that is just too good to pass up. It's 1637 miles and delivers in 53 hours so there's plenty of time to get to the delivery. You only have to drive a few miles to make the pickup. The world is a wonderful place. It pays contract rate, for discussion we'll call that 96cpm incl the fsc (van rate but feel free to change to whatever rate you choose).
About 200 miles away from the delivery you are contacted with a load offer. It's around 160 miles to the pickup from your delivery. There is no dh pay to the pickup. It is also a little over 1600 loaded miles, ending in southeast Michigan so you deliver in a good area. It is only paying 60cpm, not your contract rate. That's also all in, no extra fsc added.
Whaaaaat? No fsc? Not my usual full rate? What are you, insane!? That's one point of view.
Whaaaaat? No waiting time? No detention? No time break between jobs? Insane! Yes! Yes! Yes! That's another point of view.
So driver A says yes, delivers, goes to the pickup and delivers again back in Michigan. Total, 6 days, 3300 miles and $2550, 77cpm and $425 per day.
Purists will say no and immediately turn it down. Just say no to cheap freight. They know if they wait they'll get a proper load. So they wait, and they wait, and turns out they're right, 3 days later they get a load paying their usual 96cpm. Yeah, it's only 950 miles with no follow up job at the end so most likely more waiting for another "real" job, maybe a day from the Memphis area. So with driver B we have 9 days, 2800 miles and $2475, 89cpm and $275 per day.
Driver B did much better per mile of course. Driver B also saved 500 miles worth of expenses and 500 miles worth of wear and tear.
Oh, then you also have driver C who takes the good starter job and figures on getting back to Memphis for a follow up job. Driver C waits one day and the next day is offered a load to Memphis picking up ASAP but only paying 75cpm including fuel. Driver C says no to cheap freight, the offer of which also annoys him greatly, so he curses the day he let them talk him into taking the original load and deadheads to Memphis, unpaid, arriving within minutes of the guy who took the 75cpm load.
Let the squabbling begin.
