Employer don't even get diagnosis behind sick leave. Not sure how work accidents are treated in that regard so.

Honestly I wasn't sure how much that point applied. However with people that suffer chronic illnesses or disabilities that require special consideration I would be surprised if it was always possible to adequately communicate those needs without also mentioning information that the employee might not want to share publicly.

You can communicate special needs (e.g. "do not put this person in a loud room"), but not health information (e.g. "this person has epilepsy"). I struggle to think a special consideration a person could need that you could not just articulate instead of whatever medical issue they have (at least it has never come up for me).
