And if you are working tons of off duty because of seriously ill children, that is time you aren't spending WITH your family. Unfortunately, for too many, secondary employment becomes a cycle - they work tons of it, don't see their family, spouse spends that money and thenfinds someone else they CAN spend time with, now you are soaked for tons of child support because it will be based on your total income - not your regular wages - and you are stuck working it just to meet your child support obligations.
