I heard from a very reliable source that the IRIF planned for today was delayed two weeks—to Thursday Dec. 13. That is pretty much the last day it could be in order to get it into 2018 (since you get two weeks paid where you don’t have to come into work, followed by the 12 week lump sum severance check).
Bumping this from @WnfMsY4-1yzj for info.
