I believe in a basic universal income. ‘Disabled’ can mean a thousand different things. Plenty of people can work with reasonable adjustments and should be supported to do so. Plenty of people can’t work and deserve dignity and quality of life regardless. Most people want to work or at least be meaningfully occupied in some way, and I think people who are unable to work should have opportunities to contribute in other ways, and be supported to do so.
What I’ve tended to see a lot in workplace mental health is people who have no choice financially but to work, but their disability is such that reasonable adjustments can only go so far. For example, severe mental health conditions that involve disturbed perception of reality & extreme interpersonal difficulty, or ND conditions or OCD involving such need for control and predictability that they can’t collaborate with others. For some people in this category, work is detrimental to their health, and their behaviour at work when dysregulated can be inappropriate and harmful to others (particularly others with fragile mental health themselves, and before you know it there’s a domino effect with whole chunks of the workforce off sick with stress in particular teams and departments).
(I work with an industry that attracts highly compulsive people, so this sort of thing takes up huge amounts of HR & management & mental health time and budget and it’s not at all clear what the answer is - when someone is intellectually very well suited to a job but emotionally unstable, often out of touch with reality, and incapable of working constructively with others.)
