That is not true for wast majority of jobs where boss sets time ... and pretty often have reason for it. And schools won't adjust schedule just for you personally.
Nor clubs nor churches and even friends when they do party they set time.

Yes, because the rest of society also changes their schedules, in sync. Most people don't have the ability to unilaterally change when they work irrespective of everyone else. If they did, switching between DST and standard time wouldn't matter either—just tell your boss you'll be coming into work an hour "later" in the summer.
