Sick Leave

So I am sitting at home using up some of my sick leave.  I recently got surgery and so will have to be out of action at the BCFD for a while.  I was reading an article this morning about how some Clark County, NV FFs apparently scammed their system by taking over 1000 hours of sick leave and then working 1000 hours of overtime in a year's time.  I don't see how this is possible without some type of management collusion bearing in mind that on our usual 24/48 shift schedule we work just under 3000 hours a year.  (You would have to really be hustling to make another 1000 hours.)  At the BCFD we are required to submit a note after 4 separate shifts off; and three shifts off in a row earns you a trip to our medical clinic for a review by our fire surgeon.  I suspect that as usual the press has left out some salient details.   Here is the link for those that want to read it.  www.lvrj.com/news/firefighters-sick-leave-theater-makes-you-laugh-until-you-cry-115171014.html
