I wouldn't get too obsessed with the 2 month WARN period as they don't have to respect it. They can eliminate your position on 12/29 and pay you the two months salary in one lump sum then. It will still appear on the books for 2023. My ex employer did just that. The HR and the Security will show up in your cubicle with a box, will escort you to HR office to sign some documents and then you will be shown the door. I survived a few layoffs at CS but I don't really know the process here. There are a few excellent posts here on the topic. But to reiterate, they do not have to give 2 month notice.
"How Does Pay in Lieu of Notice Work?
When an employer decides to terminate an employee without notice, the employee may be entitled to wages they would have earned during a required notification period."
