Even if the cabin crew call sick for a head cold (something one wouldn't normally go to the doctor for, but wouldn't want to fly with), it is mandatory for them to go to the doctor for a sick note. As instructed by the company. No choice.
So if you take into account that the cabin crew have to work with hundreds of people all breathing the same pressurized air for hours on end and that going to work with a small cold could make your entire crew sick, then calling in a few more times than the average ground dwelling person is likely. A couple head colds, a flu, some food poisoning (common in world travel), and maybe having a couple nasty times-o-the month
and there you go; ten mandatory doctor visits within a year.
And, trust me, you would rather have your crew who are responsible for your safety (as you so rightly mention) calling sick versus flying sick now wouldn't you?
How ridiculous is it that they have to go to the doctor every time? Flight crew with Cathay do not. Only if they are sick over a number of consecutive days in a row.
Hope this helps.
