I agree absolutely that this was mishandled, but my point (which you deflected) is that the crew accommodation isn’t a choice. Assuming there was another available flight for the crew that did not break crew rest rules, that would have been a much, much better solution.
However - your example was that an employee wanted the screen door, not that they were required to have it.
United is not blameless here, but the analogy you used is inappropriate.
