We Lower Your Turnover Rate
"Since the average turnover among employees is roughly 25% per year, the lost impact of wellness programs is, on average, highly detrimental to the ROI from wellness investments. While there have been few long-term studies of multi-year effects of wellness investments on individual employees who participate throughout these years, the experience of the pharmaceutical firm Glaxo Smith Kline, which followed a cohort of over 6000 of its employees for four years is at least an illustration of typical patterns.
The net gains from its wellness program amounted to $613 per employee per year but increased from year to year - from $233 in the first year to $375 in the second, then $944 in the third, and $950 in the fourth. This pattern suggests a "law of diminishing returns" effect by the third year, but demonstrates how much effects and thereby ROI can increase over time among individual participants. Fortunately, wellness programs have been shown by numerous studies to be a major factor in reducing turnover, so wellness investments can improve their ROI over time through both the direct impact on employee health-related costs and productivity, as well as an indirect effect through lower turnover."
