HR is covering their tracks, they deleted many posts in an effort to hide things. Everyone will be gone soon. There is nothing left. If someone buys the product line then they will only need one or two people to do the transition and all the rest will be laid off.
We had very little administrative help. Employee files where being exposed to certain individuals. Salaries where not protected. Promotions where not protected. Bonuses where driven by corruption and there was no intervention
all of that is moot, there are so few people left. If you are sitting alone is an empty building there really is no need for HR.
