Retailer CVS was in the news Tuesday for requiring that all of its 200,000 employees who participate in the company’s health-insurance plan get a health screening (paid for by CVS) that assesses their weight, height, body fat and cholesterol levels-or pay some $600 more for their health coverage a year. The Boston Herald, followed by publications including the Los Angeles Times and Gawker, reported that if employees do not submit to the health assessment by May 1 then their annual health insurance costs will increase.
