wanna say you are right. maybe the impact is different on neurodivergent, thats hard to have hard data on. HRs job is litterally to use a certain budget to fit all the ppl in, thats why they never give a raise if you dont ask, unless they need to give it to cover other risks (retention).
best lesson for me was an HR manager explaining it to me, after finally after 3 years i asked pretty please to give a lil raise, i was still trainee after all that time.
he smiled and said he thought id never ask. made me senior on the department matching my input. and told me this exact fact. He said, why should i give you a raise if you seem happy where ur at? never complain, never ask, never get.
its harsh but its good to understand certain hashness. Then you can work around it, step over that bridge, and be more active in tracking your input, their expectations, and showing them the mismatch deservant of a raise or promotion.
its often peoples shyness or false expectations that get them in such a situation where they feel very under valued. they are because they under value themselves or dont know how to translate/express their value to another persons perspective. another harsh truth. Especially if you are neurodivergent, the way you see things and another is further apart, so your words need to do more to reconcile that difference to generate mutual understanding.
in an ideal world this would not happen or be needed, ofcourse. but we dont live in an ideal world, and there is no switch to flip to make it an ideal world.
