There's a lot of anxiety and speculation going on now, and I just wanted to post a friendly reminder to take care of yourself. You're not alone in being anxious, losing sleep, and struggling to function at work. (I am too!) But so far, all we have are rumors, and nothing is confirmed yet. Time will tell.
Also, getting laid off is better than getting fired or quitting, because getting laid off usually comes with severance pay and potentially qualifies you for unemployment if you can't find another job before the severance runs out. All things considered, I would prefer that over enduring through RTO and other nonsense meant to encourage us to quit. So the best thing you can do for yourself is to try to focus on work and not give them any reason to fire you while we wait this out. (Easier said than done, I know...) Meanwhile, dust off the old resume and make some connections. Collect any personal effects from the office before Tuesday. Take care of your mental health.
