I think we disagree on the "many". I would say "some" instead. Most people i know don't have a choice: they're employed in a shop somewhere or work from specific offices. Of course, the HN crowd may be more exposed to work-from-home, but that's still alien to a great part of the population, especially those who work the most precarious jobs.
I'm not sure how it is in Austria, but here in the US, people on the more "precarious" end of the spectrum (non-management retail and hospitality workers) have a quit rate of (very roughly) ~50% per year. So generally they do seem to be aware that they can choose a different place to work. Do you live somewhere very rural?
Yes i reside in a less populous area (south France) where you can be happy to find a job at all, if that's what you're looking for in life. But from my understanding of bigger agglomerations: there's a high turnover rate in precarious jobs, but just because you can afford to find another precarious job elsewhere doesn't mean you get the privilege to choose where precisely. I hear in suburbs of capitals like Berlin or Paris it's not uncommon for people to travel 2-4h daily to work and back. Chances are if you switch jobs, you might have the same travel times, but to a different location.
