For those of you over 40 and who still haven't signed but are planning to review with a lawyer, I want to share this. The "ADEA Group Information Notification - SIRP" itemizes those released/retained by age, SG, and classification.
I'm planning to tell who I consult the people I know of who were suddenly classified into HTHD, declassified from that designation, promoted, demoted, and especially transferred in and out. A lot of this may have happened in hopes of them getting their groupings just right prior to the mass firings. Also, it appears people were intentionally added or omitted to my sheet to probably to help their cause, as a number of them have very different skills, degrees, etc. I know the approximate age of my workmates and can back into it that way.
