It starts with a one hour group training session.
People can take what they learn back to their desks and make a difference right away.
At the least, they'll have learned that they shouldn't take their health for granted at work, that being comfortable matters, and that there are a lot of simple things you can do to be safe and avoid cumulative trauma injuries. Work strategies - health, computer shortcuts, etc. And then your Onsight ergonomics consultant will spend the rest of the day meeting informally with people at their workstations. They'll adjust chairs, make whatever changes they see - which is a lot. Keyboards, monitors, telephones, leg room, lighting, paperwork, and all sorts of details that make a significant difference in physical comfort.
