Can employees sue employers?

Can employees sue employers?
by Robert G Parent

There is an idea going around the Internet and on TV, which is that employers say they have the right to ask an employee to lose weight or lose their job. If employers can do that, can an employee sue the employer for helping them become overweight by supplying them with junk food, including Coke and Pepsi that is in lunchroom vending machines? Also, what about luncheons that companies have for their employees at holidays and special times throughout the year to celebrate a variety of events, usually what's served is fat foods? Also, if an employer forces an employee to lose weight, should the employer also pay the cost for diet programs, like Jenny Craig, NutriSystem, WeightWatchers or other programs to help the employee lose weight? Who will decide what plan the employee uses? And if the plan doesn't work, what then? I think that the path these employers are going down could harm them in their overall running of their business and could lead their company to some bad PR and a lack of finding good employees to work at that company. I mean, if companies force employees on this personal behavior, what else would they force their employees to do? But an employer that supports, not force, their employees will gain a loyal employee. Isn't it cheaper and more stable to keep employees then to fire and try and get more employees?
