If we switch to permanent DST, and the whole of society compensates by setting schedules back an hour, all we’ve done is create de-facto permanent standard time. That’s the best-case scenario.

I have a better idea. Let’s just actually switch to permanent standard time, so we don’t have to hope that society shakes itself out.

I highly doubt that would actually happen, though. During the last year, we've encouraged folks to work at home and schools have been closed. Yet those folks that work retail or healthcare or factories still had to go to work like normal. Considering how much of the population that covers, I highly doubt folks would be changing their schedules.

After all, if one group of folks can figure out how to work around the change, there is no reason for everyone else to need changes.

Exactly. We, the people, need to exert back pressure on a deeply flawed system to force it to happen. Such a change wouldn't be nearly as problematic if union membership, for example, was widespread.

How does union membership help align a work team that needs two members for a team job (for task-related or safety-related reasons) and exactly one of the two needs to change schedules because their kid's school changed schedule by an hour?

A lot of elementary schools have before and after school programs so it'll be a mixed bag.
