Not here to contribute to saying a layoff is/isn’t gonna happen.
That being said, I took 0 hours of PTO when I was laid off. I was surprised when I had my PTO hours paid out to me in cash. That and equity all paid out to me in a lump sum for each.
So, if you believe you’re getting the axe… don’t take PTO. You’ll be paid a bit more extra as a parting gift.
