it is simple 23th December is the last working day for those laid off .... work back a max 5 weeks (some countries require 5 weeks notice for older employees), so based on that 18th November will be the last day of layoffs for 2022!!!!
I think this poster hit the nail on the head. Some of us will be lucky to learn right away what our fate will be, some will find out throughout this and part of next month, but it should all be clear by November 18.
