I believe it is legal. I recently read about franchisees of fast food restaurants who are doing just this. One person owns one franchise for Hamburger, Inc. in one neighborhood, and another person owns the franchise for Hamburger, Inc. in the neighborhood down the road. They agree to hire the same person on a part-time basis, and coordinate hours. That way, the worker gets to work more hours, but each employer keeps them below 30 hours and avoids ObamaCare.
sounds like a good idea to me
Almost exactly the scenario I was thinking of.
