Pay mechanics fairly

I have friends and family that are dealership mechanics, and it's really annoying to see them not get paid for manufacturer warranty work. A number of states have put laws in place to make auto manufacturers pay their dealers the same as a customer when warranty work is needed on a new vehicle. Texas needs one of these laws. It's important a Texas law close the loophole where, say, changing a steering rack on a 4x4 gets charged the same as a 2wd, or other cases where the book time is not based on the actual vehicle getting work done. Different trim and options take different amounts of work, but boy howdy is corporate not interested in paying. Our mechanics are feeling it on their paycheck.
