my opinion only, and how I enforce with the exempts that report to me...if you show up to work and then need to leave for appointment or because ill, I don't require you to use PTO...you were at work. some in our company agree with this process, others don't, and require them to log time.
none of my exempts work a straight 40 anyway, all are over, and some are way over, 40 hours.
but as already said, follow your HR rules, and if one not in place, create one that you consistently follow.
