According to scheduling as a reserve that is in a 12 hour rest period prior to an assignment such as short call, one must have 10 hrs rest from the time they call you for the green slip. I was told when they started calling one by one at 1230 am I was legal for the 1000am green slip, but by the time they got to me at 330 am I wasn’t because of the rest, the latter does not make sense.
