I’m personally more productive and happy in open office layouts due to ease of communication and the psychology of a pseudo-computer lab setting. Granted I recognize I’m likely in a minority here. I even came from large personal offices and prefer the open office layout
I don’t mean to be rude, but you don’t know what I’m working on :). Anyway I agree that adhd posses obstacles and I’ll consider your advice to avoid some of them should I be in the situation you’ve outlined
As someone with ADHD, this is strikes me as overblown. I certainly wouldn’t require dedicated personnel to compensate for my ADHD. Especially if medicated.
