Over here in Germany there's no sick pay when you're self employed, but there is (by law) when you are an employee.
I had been self employed from my 20s to 50s and am an employee for 6 years now.
I was in hospital last week to get my back fixed and am on sick leave for 4-6 weeks now. It's still fucking amazing to me, that I can heal up now and will still get my payment into my account end of the month.
Having things like that written into law is amazing.
