If the company is paying a severance, it seems to make sense that the individual is restricted from future employment.  The more important aspect at this point is whether or not the severance is fair and equitable.  Perhaps a good question here is why is the parent so directly involved in this?  The presence of "helicopter parents" seems to be increasingly prevalent and it most likely does more harm than good.  With all  due respect, the individual needs to grow up and take responsibility for her own situation.
