Answer:
Universities and corporations are willing to pay employees to take care of themselves because healthy employees perform more efficiently, increasing the organization's efficiency and improving productivity.
Healthy employees also lower the organization's total costs by reducing absenteeism and premature retirements. Wellness programs generally reduce the insurance premiums paid by the employers, therefore some costs are offset by lower premiums.
On the other hand, once employees obtain health care insurance, their motivation to maintain a healthy lifestyle is negatively affected.
