Oh I love the old 'worse than the average' argument. Of course 50% of employees perform lower than average on any one individual criteria. That's the nature of an average. it would be very pertinent to ask if you fall outside the normal distribution for sickness (watch them look baffled by this) and then ask them if the population for EMTs matches that for Dispatchers (I bet as hell it won't). Keep your chin up Sir. It's not easy being on sick report (I have been in the same situation and it stings, I know) but hold your head high, because you know the truth.
