You give far too much credit to our governments. It was just a few years ago, maybe during Covid, that our government decided in their great wisdom to extend the return to standard daylight into November in order to improve energy savings.
Studies have been done several times over the various years daylight saving time was implemented or repealed. All showed there was no real energy savings, just shifted the usage period.
Ontario and BC have decided that they will move to eliminate DST when the states south of them decide to. They make claims that it interferes with business if they are not on the same time. Seems that doesn't bother Arizona or Saskatchewan. South Easter BC used to stay on STD time year around. So part of the time there were with Alberta and the rest of the time they were with the rest of BC. Their major trading is with southern Alberta as it is closer than the rest of BC.
I have worked on projects with partners in the UK, Germany, France, India, Shanghai, NY state, and Ohio at the same time and never had trouble with communications with them. With UK, France, and Germany, we could conference in the morning my time, and any revisions end of day or next morning. Just part of business to make things fit. Sometimes coming in an hour earlier, or staying an hour later, pretty much my typical day anyhow.
It's time to get rid of this flip-flopping back and forth. It is healthier to be on a STD time and far fewer accidents and heart attacks in the 2 weeks following each change while people are having to readjust.
For shift workers, make no difference as they are always changing their awake hours according to their shift schedule.
My rant, done.
