Let's not conflate things here.
It's trivial to click the "I've got a disability" box when applying for a job, and it doesn't necessarily mean you're disabled or have a disability, except per the definition of law.
Eg. things like alcoholism, prior or current, ADHD/autism, prior cancer, anxiety disorders, and/or being morbidly obese.
Also covered under the ADA, would be something like ripping a tendon or breaking a knee in a sporting activity and needing to (temporarily, albeit for more than several weeks) walk with a cane or need other special considerations.
I don't NOT have sympathy for a lot of these, but they're hardly a basis on which a person shouldn't be able to come to the office.
(That also doesn't change the fact that these RTO efforts are draconian and stupid, and 100% aren't being used for honest purposes by Amazon.)
