All of the Department Managers who were laid off were also included in the schedule weeks ahead of time when they got laid off. Being on the schedule means nothing, layoffs can happen at any time if they do happen.
I hate to be a "Negative Nelly", I'm just a realist. There have been warnings and clues... The writing is on the wall, and best to brace yourselves for any upcoming changes. There's a constant musical chairs game that DMs and RMs love to play with SMs, seniors, and Dept supervisors, so change is a constant with this company.
I'm holding on for now, but I'm expecting the worst and hoping for the best. From what I've heard, maybe getting laid off isn't such a bad thing. Severance + getting paid out for your remaining PTO, plus un employment $$$? I would just take it as a free vacation. Lol
