One possible upside is that if you pull a knucklehead move and forget to call in well, AND the scheduler does not give you a courtesy call to inquire your status, you don't commute in just to find out that the schedulers assigned your trip to a reserve. Thus, while you will still get paid for the second trip, your sick bank will take another hit and you might open yourself up to monitoring status. As a side note, I have been called by scheduling as in this scenario. I did not consider it "sick leave harassment" as some here would and was most thankful that I got the courtesy call. I don't consider it harassment 'cause the scheduler could GAS...he just cares about getting all the trips covered and he has a lot of arrows in his quiver to accomplish that, the first being to check to make sure that it wasn't an oversight on your part.

YMMV
