If you get a second job, you will be hauled back in for a modification hearing, because you are making more money, and your support amout will go up...trust me. The more you make, the more the mother will get for support. period. It does not matter that you got a second job so you can afford your bills.

I know this is not what you want to hear, but that is just the way the child support system works. I'm not sure about your state laws, but in PA, they can take 55% of your wages if you are only supporting one child/family. What percent of your paycheck are they taking? If they are taking more than that, you might have a reason to appeal it.
