CJEU Judgments – parttime workers get overtime from first extra hour

Hi, I am curious. The recent EU judgments that say a parttime worker should get overtime pay from the first hour she/he works extra….are these groundbreaking news in Germany? Will it change much?

Or are fulltime jobs outnumbering parttime jobs so that these judgments will not affect so many?
I am from Norway, and here many thousands of people work parttime. And very much so in the healthcare sector, because working 100% is too stressful.
