A colleague I manage has ADHD. I've always been more than happy to accommodate and I've asked them several times what adaptations need to be made to brief in tasks etc
They've never been forthcoming with specific recommendations and it's always been vague so I've done my best and given them double the amount of time with tasks, ensured briefs are crystal clear with deadlines and regularly checked in and offered to help.
For a recent task I gave them double the amount of time I would give myself, sent them a brief and made sure they weren't given too many other tasks that week so they could concentrate on this one. I've always made clear that if they have difficulties for whatever reason, they need to let me know.
They left the task to the last minute and didn't do half of it so I had to step in and do a lot myself at the eleventh hour in order to avoid missing a client deadline. They didn't communicate difficulties at any point until I checked in. I'm at a loss as to what they were actually doing in the week I gave them to do the task.
When I pulled them up on it and asked what had happened, they mention the limitations of their condition straight away and explain how they have trouble with things like prioritising and focusing. Yet they didn't reach out once to explain this or ask me to brief in a different way to make it easier for them.
Have I been unreasonable here? I'm not pretending I have the answers but I have tried all I can think of to accommodate yet its not working and they're not really giving me much guidance on what they need yet it's always the reason why they can't do the work I set.
Meanwhile I'm taking on lots of extra work so as not to overload them yet they struggle with completing one single task. No idea what to do.
