You might want to check your local child support laws, I know that here, if the NC Parent quits their job, they won't change the amount of support that they owe, and in some cases the judge can pretty much force the NC parent to get a job. Too bad she's only doing a McDonalds job, though I suppose 55% of crap wages is still something. That could be the mom's wakeup call though to do something with her life. I can't imagine someone being able to survive on 100% of a McD's salary, let alone 45%
