Ok but for most people work hours are dictated by a shared clock (and many daily activities as well) so... It becomes a coordination problem if we don't all agree on what time it is in each locale.
Considering that one of the biggest problems in our country today is trying to run more and more at the federal level instead of at the state level, it's really silly to add to that pile.
Changing time zones or keeping permanent daylight time requires a dispensation. It is my firm belief that state legislatures have voted to keep permanent daylight time as a way to not actually change anything while telling constituents that they're doing stuff.
At one point a couple New England states were looking at this, but for that reason it would have been implemented by moving to a different time zone: year round AST rather than year round EDT. (Which are both UTC-4.) That said, I think states need federal permission to move time zones, too.
Right now, the revealed preference is that there is zero demand for it.
And by what metric is there zero demand to solve the time-change problem?
Obviously request a reasonable accommodation and sue if you don’t get it.
