- the scenarios you describe/have experienced would not be applicable. The fact that they are in your outfit (assuming you're a pilot) is utterly atrocious.
You mean - having to produce a Sick Cert?
I've worked in a couple of airlines, including majors, and a Sick Cert is required in all of them, bar a few days self certified (where you may receive a company doctor visit). If you think that's atrocious you must live in a bubble, and I'm really keen to check your OMA now to read all about it.
By the way - the system I work under is approved by the CAD. The same one that approves your own OMA.
