It's posts like this that make me glad you are back Greg..
Haul the freight at a rate you can live with, if you think the rate is low DON"T TAKE THE LOAD!! Just because somewhere in the accounting books the customer paid a lot more doesn't mean you deserve it. Every division of a company needs to take their cut, just like a load that has gone through a few brokers before it gets to you. Bottom line is the decision to take the freight at a given rate is yours.....nobody else.
Just playing the devil's advocate, Why indicate paying a percentage at all with your theory? You are saying if a customer paid more, you may not necessarily deserve it.
By what and who's measure? If you decide you don't deserve it, should you be paid based on your contractual percentage regardless? Just curious, but I understand what you are thinking. With depressed freight/rates, I think you will see more pass-throughs as carriers try to maintain their previous profit margins. I agree that it applies to brokers as well.
The downside for operators is you wind up running for less in these cases because others will run for so little.
