I never understood why people don't just go sick, sick and more sick = hourly pay increase = be home with friends, family - whatever.. It's not that hard - you just gotta not give a rat's ass about at company that doesn't give a rat's ass about you.
Excuse my ignorance, but doesn't CX require Sick Certs to back up sick leave?
In my experience HK doctors won't give Certs out so easy. I've been through this - had fevers so bad I couldn't get out of bed, but when I finally got to a doctor I was refused Certs for the days I was too ill to visit. They won't give a cert if they haven't seen you.
On another occasion I went to a doc when I started getting the onset symptoms of one of those HK fevers I've become all too familiar with. She would give me 2 sick days and no more. When I asked why she told me she'd be reported to the HK Medical Board by my employer if she gave me any more.
I bet CX have company drs too, who can make house calls, just to catch the malingerers?
Your proposal is unworkable in a mass sick out. You'll get no cooperation from the medics.
