I've never heard of the paid vacation time enshrined in law, especially as work contacts were overseen by labour trustees appointed by the DAF (German Labour Front). I don't know everything, of course.

They did have the Strength Through Joy program where they provided incentives like vacations, and Beauty of Labour which was supposed to make work places better, but

While it encouraged Germans to view cleaner work environments as important and provided guidance on how to make improvements, it did not provide funds to make necessary changes. Paying for improvements remained the responsibility of factory owners and managers, or workers themselves.

These were programs designed to get buy-in despite the deterioration of workers rights, including hours of work and pay after the Nazis came to power.

The infrastructure program was the Reich Labour Service. It was a mandatory program, and workers lived in camps working long hours with low pay.

Unemployment was illegal, not abolished through the creation of good jobs. In 1938 Aktion Arbeitsscheu Reich arrested the "work shy" and send them to camps.

Germany had nationalized health insurance since 1883.

There were massive infrastructure jobs programs which led to almost zero unemployment.

Lmao! They had low unemployment because trying to conquer Europe takes a lot of work. Notably, in spite of the low unemployment, the working conditions were shit and the workers could not organize due to violent suppression.

You might as well argue that slavery is progressive since it means low unemployment.
