Spend your time getting prepared in case it does happen. Make sure your resume is in good shape, download your contact list and minimize the amount of personal stuff you have at the office. Even if you don't get laid off, you will be well served to have your stuff organized and ready to go.
Exactly this. Being prepared can mean a world of difference. I'd just like to add to what @foq+19caBejv said, update your linkedin and renew and stay in contact with people who could help you with a possible job prospect in the future. Layoffs can catch you with your pants down or fully prepared. It's really on you which one it's going to be.
