I see no way on Earth that the cuts don't start next week and occur in some rolling fashion across the company with a goal of completing them by the end of January. There is NO way they have enough security in place to escort all those people at the GM Tech Center or Ren Cen offsite at the same time. Also one must consider the logistics involved in having these folks turn in their laptops and GM property and the fact that their access to GM online systems needs to be shut down ASAP. So things like their AD account and VPN access needs to be shut down. No way could 6000 folks be done all at once.
