This is wrong, because you’re talking about disability insurance in a comment thread about disability discrimination.
Disability is very broadly defined for the purpose of disability discrimination laws, which is the context of this comment chain.
Disability is defined specific to a person’s work skills for the purpose of long term disability insurance (like the US’s federally administered Social Security disability insurance). Depending on the program/insurance type, it might require that you can’t hold down any meaningful job, caused by a medical condition that lasts longer than a year.
For things like short term disability, the disability is defined specific to that person’s preexisting job. Someone who gets an Achilles surgery that prevents them from operating the pedals of a motor vehicle for a few weeks would be “disabled” for the purpose of short term disability insurance if they’re a truck driver, and might not even be disabled if their day job is something like being a telemarketer who sits at a desk for their job.
