So they are not even following their own memo.......

If the last day off schedule check is not required now (even mentions that in the memo I believe, and can't be required per fars?) and you go on long call at midnight, a 10am short call doesn't work as there is no prospective 10 hours of rest after notification. Even per the memo you have 2 hours to respond under the worst case scenario. So if they call at midnight for 10am short call, and you don't respond until 0145, 10am short call doesn't work for the far's.

EDIT for reference: "Part 117 requires that a long call reserve pilot be given at least 10 hours of rest prior to starting an assigned FDP or reserve availibility period (RAP)....rest must be prospective in nature, so the pilot must acknowledge any fdp or rap no later than 10 hours prior......"
