I'd also add that the culture allows and encourages sick days. The average is 15 sick days per year IIRC.
In New Zealand we get a minimum of 10 sick working days per year but some companies offer more and allow unused sick leave to accumulate.
And there's an unlimited number of sick days. As long as you have a doctor's note, you still get paid, up to some ridiculous limit at which you might have to get government support instead.
Many countries have this system and the usual effect is that the duration people are sick for is magically never less than 2 days. It's dumb policy.
For example, the way it works in Australia is that after you have used up your sick days, you have to take any further absences from work out of your annual leave balance, and once that is exhausted, you switch to leave without pay.
I had a downline team member who once needed to extend their time away from work for over 5 months due to illness. They had been with the company for several years at that point, so they had a reasonable sick leave balance, probably 10 weeks. When it became clear that they needed longer, they used their remaining 4 weeks of annual leave, then took a month of leave without pay, then another. They were still employed, I approved their leave requests each time they needed to extend, and we just used the most appropriate tool that was available at the time.
The thing you're getting permission for is not to be sick, it is to be considered still employed while not doing work, rather than being fired/disciplined for being AWOL.
15 is the average. I use it to reassure people that it's okay to take sick days, and not one of those rights that no one dares to use.
Usually, employers ask for a doctors' note after 3 consecutive sick days, but the reason for the sickness remains hidden from the employer. The note just gives a time range, nothing more.
Now I wonder if I could help the immigrants in my area (I'm in Hesse/Hessen), thanks for the inspiration too.
