I'm in Sweden and we did several of the things that article says we didn't do. In Sweden we have a legal right to unlimited time off when we are sick. During the pandemic, we were instructed to stay home and collect our paid time off if we had even the slightest symptom. Starting after a few months into the pandemic, everyone who could work from home was required to do so. In places of work where it was impossible to work from home, strict social distancing rules were in place.
That article makes some other questionable assertions, for example claiming it's an indisputable fact that Covid was manufactured in a lab.
