Our vacation bidding flexibility is the only thing that allows me to safely do this job. Whether it is several months in a row night hub turning or international flying, my sleep debt continually builds. But after using my vacation to set aside 3-4 weeks of off time, my batteries are recharged and I feel great. Take away my ability to do that and at some point my health and flying performance will suffer. So if one of the goals of PBS is to allow only one week of guaranteed time off, we cannot allow that to happen.
