CVS Lays Out Employee Insurance Guidelines [AUDIO]

CVS Caremark has told its employees that they need to reveal their weight and undergo blood tests, or pay an extra $50 a month for health insurance.

The CVS policy also says, "Going forward, you'll be expected not to just know your weight and blood pressure, but also take action to manage them."

"Maybe it is fair that people who smoke and disregard their health should pay a little extra," one woman told us.

"There are no penalties based on the results of a wellness screening," a CVS spokesman told NBCNews via email. "Choosing not to have a screening will result in a $50/month increase."

Many companies have long bemoaned soaring employee health care costs.

"Most employers, like CVS, go from no program at all, to a coercive program," Lewis Maltby of the Princeton-based Workrights Institute said. "They don't even try to help."

Instead of this, "carrot-and-stick approach," some companies have gone the incentive route, offering rewards for better health.

Rhode Island-based CVS has about 200,000 employees nationwide.
