Message repetition matters. Sending a single “all staff” email introducing a new wellness initiative is unlikely to yield significant effect in itself. Capitalize on existing communications channels, and don’t be afraid to employ new ones. Emails, newsletters and staff meetings are tried and true mechanisms for reaching employees. But don’t forget about events (think healthy cooking demonstrations), text messages, Tweets, podcasts, videos and the array of creative opportunities when you view the walls, stairs, elevators and other surfaces in your workplace as a blank canvas awaiting your message.
