David, Yours is an interesting answer, because you recognized that the individuals ADHD may effect the non-work aspects (at least, not the pieces they were hired to do) of their performance, and that their failure to adhere to work expectations may impact on their ability to hold a job, even if they are really good at the job itself! You are absolutely right -- but it is a side of the problem that rarely gets discussed. Just as we tend to focus on issues of attention in the classroom or attention on tests (when discussing ADHD in education), how the disability impacts on time management for studying, or on remembering assignments and keeping track of due dates can have just as much of an impact.
