Ask HN: How to prepare for layoffs as a Senior Engineering Manager?

Context: I am a senior EM (manager of managers) at a company I've been at for about 7 years now. I started as an IC with minimal other job experience and grew to a senior engineering manager.

There's no indication at this point that our company will have layoffs (revenue strong, still hiring albeit a bit slower, etc) but I want to prepare for the potential.

1. What can I do to prepare myself incase of surprising layoffs?

2. Do you folks think it would be possible for me to take a job being a leaf node / front line EM again? I see way more of those than I do sr EM and I'm totally fine with a paycut. In fact, in some ways I enjoyed that job a bit more and would be happy to take that role again.

3. How do folks stay from getting worried? I have no reason really, my team is strong, I have gotten consistently high ratings, no indication from the company, but I still feel scared every day.
