> Only in emergencies, and even then only 10h a day.
Are you saying that if there's some major medical incident, with medical facilities overwhelmed, hundreds of people needing help, German doctors would just say 'sorry, ten hours, I'm off home to watch TV'. I'm sure that's not true.
The grandparent is slightly wrong. You are allowed to work 10 hours if your average over the next 6 months or 24 weeks does not exceed 8 hours a day. (Where "day" includes Saturdays but excludes Sundays and holidays)
There are a number of exceptions for extraordinary situations, that could not have been anticipated by the employer, to allow exceeding the 10 hours. However the rule about the average in the next 6 months or 24 weeks still applies.
