He may or may not have been let go in a future round of eliminations just like anyone else. I believe he made a mistake thinking it was a hint. They did not target down to the individual, they offered it to chosen orgs/groups, if you were in those groups and met age, time in service and band level requirements, it was offered to you.
I know a few who denied the summer round who are still here, where others on the team (under 55) were then let go. The numbers do not support the theory that if you deny it, you are gone in the next round. 4,000 or so in the summer round refused the VRP, not sure how many thousands refused the January offer.
It's a personal choice, I think it's a good program, and would be happy to take it if offered to our group. (I did try asking for it, that didn't work). While this is new to this company, it's been a common tool used for years in many companies.
