I've been in the tech industry for 45 years. Layoffs happen regularly. Well, not regularly, what it is is a chaotic system. There will be good times and bad times. The best way to deal with it is to immediately save, at a minimum, 6 months of runway. Preferably a year.

When you're in between jobs, work on:

1. improving your job skills

2. network

3. build your resume by contributing to open source

4. start your own business
