It’s Constitution Day in Denmark, which is another of the holidays only observed by half the businesses, making everything in the country frustrating and disfunctional.
You see the government and firms with a heavy union presence close, but private and international businesses mostly don’t. Trains run on a minimal service, daycare closes and so do schools. Thus you are forced to either take the day off or battle against the odds to get to the office.
These half days are in general are a waste of time and very detrimental to productivity. Given that there is less than a month to July, when the entire country goes on vacation and the country grinds to a halt for a month, I question the sanity of half days. Either make them full vacation days or cancel them altogether. Either they are important or they are not. Half days are pointless and hell for those who work them.
