Design experts are working with companies to nudge employees in a healthier direction without them noticing. Active design, the latest trend in office planning, uses workspaces to nudge workers into making healthier choices. That means bathrooms that may feel unduly far from one's desk, or a staircase that's easier to access than the escalator. Companies have increasingly enrolled their employees in voluntary, and not-so-voluntary, initiatives to promote good health and fitness, but active design requires no buy-in. It's invisible, which eliminates a lot of the pitfalls of employee-sponsored wellness programs. "When they're mishandled, wellness programs become platforms for shame, embarrassment, and disappointment," said Danna Korn, chief executive officer of the Sonic Boom Wellness program.
