1) Why does one need to hear to operate a cash register? My local WalMart has a checker who appears to have a hearing deficiency, as her speech is somewhat difficult to understand — but she’s friendly, efficient, and not least, a gainfully employed & productive member of society.

2) Also, have you ever done a ride-along with cops? My kid is a cop & I’ve done several: In many jurisdictions, it’s SOP for an available second officer to arrive to assist at a traffic stop, a domestic call, pretty much any incident whatsoever. There was a reason they used to patrol as two officers in a unit — but budgets now dictate otherwise. So…, backup unit. The sex of an officer has nothing to do with it.

A local farm store has/had a deaf girl running a cash register. She reads lips.

In our system we have employer provided insurance which creates some problems. The insurance covers more than just employment related events, it covers all events. A clerical job with very tiny risk to a hemophiliac might be held by someone who has a risky recreational interest. I was on the community board of a small company that had a man with hemophilia in a very safe job position, but he was very involved in off-road motorcycling which resulted in some tremendous bills. Screening to keep hemophiliacs out of certain positions due to the hazards of those positions requires screening their off duty activities as well. The practical result would be that they become unemployable.
