The only way to combat this is forcing them to "badge-out" as they leave the building. Depending on how the door system works, they may already have to do this.

As is almost always the case with RFID applications, it's easy to know
when someone/thing arrives at a location. The bigger (and harder to
answer) question is when did that someone/thing LEAVE a location? Is
it/him/her still there 5 hours later? 10 hours? Imagine the stack at
the EOC if you look at the last known coordinates of emergency personnel
one week after an all-hands meeting...

All we need is to ask them to send us a file or signal, and then we can convert that to APRS and send it out the EOC APRS radio and see who is there. Done!
