I'm wondering if I can get some advice from the perspective of adults round here with ADHD, or living with people with ADHD.
Long story short, professional person in their 40s (X) sent a very offensive email to a colleague (Y) in a voluntary organisation they had recently joined, copying it to a few others. X has ADHD and possibly ASD, says they were provoked by Y's conduct in a meeting and questions Y then asked in writing. X now won't apologise, but might retract the message.
The organisation wants to make all reasonable adjustments, and is thinking of putting in place a code of conduct which essentially says you mustn't be rude, offensive etc (which should be obvious anyway?). They hope that it will help X to have a defined set of rules setting boundaries. But there are concerns around the fact that X presumably can't have had the successful professional career they seem to have had without learning that this isn't acceptable, and also the fact that this reaction happened so soon after they joined. is the code of conduct going to be enough? Provocation might explain an instant reaction, for instance in the original meeting, but is it consistent with sitting down and composing a long email, and subsequently refusing to apologise? There is also the duty to protect colleagues and others from the possibility of similar attacks in the future.
I know you can't generalise about how ADHD affects people, but is X's conduct likely to be down to ADHD and possible ASD, and if so, realistically how far can anyone be sure it won't be repeated? We try to teach children with this type of difficulty how to manage in society, but I suppose when this person was growing up there was much less understanding of ADHD and therefore much less support. Ideally the organisation would like to get past this and move on with both X and Y who both have a lot to contribute, but is that realistic, and how far should they make adjustments for X?
