Here is a PTO cancellation question I have. I'm a software developer at and I'm working on a very high-impact project with tight deadlines. I got sick back in early February and ended up having a heart surgery in mid-March (I'll be out of commission through mid-April). I have a trip to Australia planned for August (5 weeks), which was approved before I got sick. I have enough PTO to cover both the trip and the sick time, but I'm afraid management may cancel the approval for this vacation time, justifying it with the fact that I'm needed for the high-impact project. My wife and three kids are coming with me on this trip, and it's something we've been planning for years. It would be a huge bummer to have to cancel it.
Do you think management can cancel my already-approved PTO?
