It's not unusual for people who have been in the same job for 15+ years to be pretty complacent. I work at a FAANG, and the two groups that you see often slack are the new folks who don't have a hard work ethic, or people who have been at the company a long time, and stopped trying to do anything but the minimum. When the layoffs hit, the most likely folks were those two extremes. Mid level people were safer. People who were there for long tenure and still were going strong seemed fairly safe too. Up and coming stars were mostly safe. As for being able to sleep well at night, the best you can do is life a lifestyle you can support with a very mediocre job for your location. That means if you get a high paying job, don't inflate your monthly expenses. Pay off debt, invest wisely.
