Another thing happening here, have not enough friends working in construction, but husband of a friend whos company working on buildings on different sites in the bigger cities got a notice last friday that he and colleagues have to stay home. Like in 100% stay home. He didn't tell why exactly, if it's shortage of construction materials as he don't know.
I posted it in the construction thread yesterday but they keep talking about shortage/high prices of lumber and quality of screws.

So he who works a trade that was and should be really in demand as there's usually a shortage of construction workers and handyman here, with many overtime hours working, is now full time at home.

It's called kurzarbeit here, as people are not let off but get paid 60% from their income (after taxes) not from their employer but from the Arbeitsamt (which is tax payers money).

Can only assume its because of lack of building material.
