I don't disagree, it was a bit alarming and while our PTO policy is better than many, there are still lots of competitive employers who offer better benefits wrt time off.

It is nice to never actually need to provide a reason/note to be out, but I think the combination does stress some of my coworkers (e.g. "I don't want to take vacation because what if I get sick", "Oh great, I'm sick, now I can't take vacation").
