Global data from 2020 estimates the rate of adult ADHD at 2.58% (yet many people remain undiagnosed, especially in minority communities). This means millions experience hurdles like Christian’s – and some don’t even know why. But even for people who do have a label for their struggles, a diagnosis isn’t necessarily a fix; many workers with ADHD experience challenges that can inhibit success. And whether they reveal their issues to managers or keep them private, the effects of ADHD follow them around in their careers, affecting their job security, career options, work relationships and even how they feel about themselves.
