The issue here is at the end of the day, there is work to do, and results matter.

Everyone has finite shits to give.

If everything is going fine, other people will often be willing to pick up slack or adjust. If other people are exhausted, overworked, or have no more shits to give - they won’t. Or more precisely, at some point they can’t. Or suffer negative outcomes themselves.

Disabilities are called that because they make things harder, for the people who have them, and for those around them. Same with disorders.
