I second this. On paper Austria has below average working hours in EU statistics but I've seen a lot of overwork in the tech companies I've been at by some people, but which was never officially reported because the workers themselves just went along with it.

Scandals in the papers around the crazy hours workers at big-4 consultancies in Vienna typically do, which again went unpunished by labor agencies, since there were no written orders from management imposing those long hours but workers just tactilely accepted it as part of the work culture there.

Similarly, a mate of mine at major finance gig in Frankfurt noticed that they were working longer hours than their colleagues from NY. Heard similar stories from colleagues from Italy and France.

So work hours are super dependent on local culture and industry. The meme about everyone in the EU being paid to slack off all day is not as common as people imagine, unless maybe you work for the government or got lucky to score a great gig in some dysfunctional monopolistic megacorp.
