>"... will change the makeup of our workforce [to] younger, whiter, more male-dominated, more neuro-normative, more able-bodied"
Was this an issue before COVID? I can see how this policy might help shape the workforce, but not how it would change the workforce from what it already is unless it became more diverse during COVID as a result of flexible WFH options.
I also understand their justification for how these might limit candidates except "whiter" and "neuro-normative", which their letter didn't seem to provide direct reasoning for. I suppose "whiter" might be the result of drawing more from the local population, but again they seem to be arguing that a policy that's still more flexible than pre-COVID will make things worse, which I don't follow.
>*"requiring everyone to relocate to the office their team
Again this shouldn't make things any worse than pre-COVID. Given that full WFH was stated as temporary then no one should need to relocate to accommodate a partial in-person requirement. Not unless they unwisely moved away during the lockdown despite things being temporary or are new hires who also failed to take the temporary status into account.
To reiterate, I'm very sympathetic to their overall complaint, but it appears that they might be doing their case a disservice by implying that this will make some things worse than they already are or were before.
