I would suggest as many affected people as possible file complaints with the EEOC. Google is facing a class action lawsuit in a California federal court for age discrimination right now.
Nike has always done this, especially in the NL. Every time it would reorganize there, the over 40's were always disproportionately targeted with layoffs because they cost too much money. I think one person managed to retire from Nike EMEA in 20 years. The EEOC can investigate and bring a court case on your behalf.
