According to a new survey by Watson Wyatt, more companies plan to offer financial incentives in the next two years to reward workers who adopt healthy lifestyles. Nearly half (46 percent) of the surveyed employers currently offer or plan to offer financial encouragement to workers who monitor and improve their health. By 2009, that number is expected to surpass 70 percent, Watson Wyatt reports. The survey also finds that companies with effective health and productivity programs demonstrate superior performance, achieving 20 percent more revenue per employee, with a 16.1 percent higher market value and deliver 57 percent higher shareholder returns.
