Tech isn't a carve-out where there are fewer protections from the state. I pointed out that I was a tech worker in California because we normally get better protections than most Americans. In this case, even for the well-protected California tech workers, there are few legal protections, if any. For other Americans it will be just as bad.

If you've been with your company for less than a year, you are legally entitled to zero days of paternity leave and if you take unpaid time off, your job is not protected.
