Businesses violating medical rights.

I've noticed a bit of controversy on the news as of late, and it's something I wanted to vent about on here.  There have been news reports about various businesses (that will remain nameless) that are forcing their employees to go to their doctors by a specific date and get physicals done.  In my opinion that is something people should be doing on a yearly basis regardless just to make sure they are in good health.  However, there is more to this story. 

According to employees, they are being forced to report their weight, body fat percentage, cholesterol, blood pressure and blood glucose.  If they fail to do so, they are fined an extra $40-$50 every month on their medical insurance which can equal up to $600 a year. 

Now correct me if I'm wrong, but isn't medical information supposed to be kept confidential between the doctor and patient?  How is this legal for a business to force you to go to the doctors and report your private information to the company?

The answers these companies give is that they want a healthier workfoce and they will not see the medical records or the numbers.  My response is, then why force them to report the information in the first place?  I believe this is another way for businesses to secretly figure out which employees are too overweight for their company and find alternative ways to terminate their employment. 

These companies are telling their employees to go to the doctor and use your medical insurance or pay a fine every month until you do so.  How is that legal.  When has been the insurance company or place of employment's decision to force their employees to visit a physician? 

This is something the government needs to step in and take action against.  People who have medical insurance should not be forced to report their medical information to anyone and should not be mandated to visit a doctor before a set date or be penalized and fined for not complying. 

Thankfully my employers do not require such a thing and trusts their employees to manage their own lives without having someone standing over them.  I urge everyone who reads this to fight back by contacting their local politicians, Congressmen, or Senators and telling them this is unlawful for companies to force their employees to go to the doctors, to report their medical information or pay a fine for not complying.
