Notified of your being let go via a personal email? So no opportunity to back up your data, save contacts (which might come in handy for finding other employment), any notes or drafts... Brilliant idea, honestly ...
You'd think a little bit of forethought would cause you to have done that at any point in the last few weeks since this shit-show started, just in case.
Literally no place I’ve ever worked in my decades in the tech industry were laid off workers allowed any physical or virtual access to company property post layoff. I’m sure it happens sometimes, in rare circumstances, but to pretend that this is especially egregious is disingenuous.
