I am a disabled person (U.S. based). I've had trouble holding jobs over the last two years. I can't reliably spend 40 hours a week in front of a desk. Hypothetically, an employer is required to provide a disabled individual with "reasonable accommodations" to complete their work tasks in the U.S., but because the only recourse a disabled individual has is legal in many cases companies are willing to risk it as they have far more legal resources than their employees.
I appreciate very much when a disabled individual speaks openly about their disability. It puts social pressure on everyone to appropriately accommodate the needs of their disabled employees. For me, it means that someday I might be treated with dignity and respect in my work again, like I was before I was disabled.
