FYI, I just heard from my (small) company. They're going to allow us to go negative on our PTO up to 40 hours. So we can use up our earned PTO (vacation time), then after that's all gone, go negative (i.e., earn it back over the upcoming months). After that, it's LWOP and applying for unemployment.
I'm not complaining, just informing.
Thanks for the information!
