This is certainly interesting to ponder. Not just for us, but for many industries. To me the biggest benefit is choice. Some people want Christmas, Easter off etc. I personally don't. I am more than happy to work public holidays etc. I hate going away in peak periods and having to put up with people's annoying offspring and crowd's etc. Choice is always a good thing.
But this could have such a huge quality of life benefit for so many people that I can't see the government letting anything happen from it. Healthcare providers would burn the country down before they give their nurse's anything.
But if COVID has taught me something, there is zero care and loyalty in this game anymore. So if you don't give me my wife's birthday off or the kids footy grand final off I sure as hell won't turning up.
