There are jobs where employers actively try to support disabled employees, and there are jobs that will grumblingly provide the bare minimum legally required by the ADA and then find some pretext to fire you (or to not hire you in the first place, if you admit your disability during the interview).

It's valuable to let companies in the first category identify themselves.

There are jobs that someone with a disability can do just as well as someone without that disability. Likewise, there are jobs where that's not the case.

Many jobs involve physical labor which is inhibited by an array of disabilities.
