The Americans with Disabilities Act Amendments Act of 2008 lists attention deficit hyperactivity disorder (ADHD) as a cognitive (mental health) disability. It requires that employers don’t discriminate against employees with ADHD. You may find that some of your employees with ADHD are falling short of certain expectations, aren’t being productive, or aren’t feeling fulfilled at their jobs despite doing their best. If that’s the case, their working conditions may need to be tweaked to help them be more successful.
