My current employer had me answer the question of whether I'm "disabled." I've never answered "yes" to this question since I've never been diagnosed with any form of neurodivergence, though therapists have suggested that there's a good chance I'd be diagnosed if I saw a specialist. But this time I noticed that my employer's definition of "disabled" included not only neurodivergence but also depression, which I do have a diagnosis for. So... now I'm disabled.

I have no idea what use the label is when it's so broadly defined. It doesn't give my employer any information that would help them support me in any way. Fingers crossed there is some benefit to it.

It probably helps the employer demonstrate that they hire and retain disabled people, likely assisting with some government quotas, and defenses against lawsuits by aggrieved ex-employees.
