Equalities monitoring is common enough, and the 'identify as ' language was useful. Ethnicity is an area where id can be complex.
On the reasonable adjustments at work, that's another tricky one. Adjustments may need to be reasonably made for people who are temporarily disabled in some way, or have things that are a standard result of ageing. Is someone who has hurt their back and needs a special chair disabled, if they are going to get better? Would they describe themselves as disabled (probably not). Should they be counted as disabled for monitoring purposes? If someone needs a special screen due to ageing eyes, they should have it. Are they disabled? Yes, would they describe themselves as such? Who knows. Questions around what people can and can't do are never going to be exhaustive and are quite personal. They might be appropriate for financial claims or insurance stuff but this info is useful in other contexts where this questioning would be overkill.
The other point is that employers do discriminate on disability, without question. If it's not obvious, will most people disclose? Maybe once got feet under desk. Tricky.
I asked earlier when you posted if you were thinking of stuff like benefits and you weren't, but conversation has moved on. Benefits claims are different and heavily scrutinised. Adjustments at work, reasonable ones, can and often are made for all sorts of people for a range of reasons. Equalities monitoring is important, though lots of people don't like it. It's more that sort of thing where it is useful to know what's going on, and would it be sensitive to probe.
I suppose the bottom line here is, that fact and truth are out the window. Anyone can id as anything, more or less. Certainly on a form that is anonymous. So it's rendered the whole thing, all the equalities and d&i etc, pointless. And the weirdest thing is, it seems that minority groups are in favour, on the whole.
