It arrives predictably each week, draining motivation from workers across industries. Although plummeting productivity on a Friday afternoon is normal, it’s not inevitable, says Billy Roberts, a therapist based in Columbus, Ohio, who treats professionals with ADHD. “The slump is sometimes a result of chronic work stress and a lack of self-care throughout the week,” and can also be triggered by anticipation of the weekend, he says. By identifying what’s contributing to your Friday energy dips, you can better power through, Roberts says.
