CVS Caremark has put its employees on notice that they need to reveal their weight or pay a monthly $50 penalty.

"Avoid the $600 annual surcharge," CVS warns its employees who use the company's health insurance plan. They've been told they are required by May 1 to show up to a doctor for an annual WebMD Wellness Review and submit to tests for blood sugar, blood pressure, cholesterol and body mass and body weight.
