In EU since Jul'23 cross-border remote work is free of extra taxes and similar obligation if done up to 50% abroad. One can come to Germany for 3 days and come back to his country to work for 2 days remotely and spend weekend.
Unfortunately this is effectively useless as you need to submit your employees one by one to get this exception. I know of an employer ($4bn revenue) who said this is simply not feasible.
EU bureaucrats are just stupid.
