New lease contract

I know what all of you are going to say. DON'T DO IT!! Well, i did and when i signed my contract it stated that i the contractor would get 100% of the fuel surcharge. Which is the way it should be. Now 3 months into it they are trying to get all of the lease guys to sign a new contract regarding fuel surcharge. In this new contract they are telling us that as of every tuesday by 12:00 they will send the new rate and that rate will be used on all trips for that week on top of your normal cpm. Now, i haul for a refer company and our bread and butter trips are meat loads. That is where we get a pretty good fuel surcharge rate. Now they are averaging it out based on the national avg for the price of diesel. I see it as being good on trips that we don't really make that much of a surcharge anyways, but when it comes to meat loads we are getting screwed. I got told that if we choose not to do it that if we get a broker load that the brokers would not pay a fuel surcharge and it was in our best interest to sign this new agreement. To me, that kind of sounds like a threat. "if you don't sign it and put more money iin our pocket we are going to starve you for miles out there and either force to you sign or quit". I see this new plan of my compay going to back fire in there face and they are going to loose alot of good drivers. They push and push for you to go lease and then they through this at you to.

My question is has anyone had this kind of stunt pulled on them or know of anyone. And what, if anything can we do about it. It's hard enough to make a living out here and now they want to just make it even harder. I'll looking forward to here your comments.
