So after settling they went out and told their kid about the settlement and, presumably, that she wasn't to discuss it, after which she posts it on FB (and in a really snotty post)?
Yeah, no, they got what they ultimatly deserved. He may have been discriminated against by his former employor, but he also raised a snot nosed brat.
I disagree about keeping your children ignorant of finachial issues, and obviously the child was aware of the situation and needed to be informed. However, the child also sounds like she's old enough to understand "confedential" and "do not discuss this with anyone."
