Very shady. Because they want the plausible deniability.

I just tell them I need notes to keep track of my conversations and refer back to them frequently because my autism and ADHD causes me to question myself or forget what was discussed.

Then if they wanna push it further I can take my records to HR and ask if they feel like allowing this ADA violation to continue. Doesn’t work for everyone, I know, but it works for me!
