Not necessarily. Yeah if you have pneumonia or strep throat or a broken bone, etc then sure, the system is air tight in your favor. See any Dr. in the world, get a note, done. But say you get a mild to moderate stomach ache or feel nauseous or have a headache, etc. There's a metric ton of things you can't/shouldn't legally fly with but aren't "verifiable" by a doctor, ever. So you get sick on or near a weekend, holiday, vacation? How about a block of days surrounded by several days off? Or several day on? You could say literally any sick call is suspicious for one reason or another, and not only a lot but probably most sick calls can never be "doctor verified" because there is no test or method to verify most minor illnesses other than patient testimony. So then what? Bottom line this ridiculous one way sophistry will end up with less sick calls to the company but more pilots flying [just a little?] sick. Guaranteed.
