Push to unionize Apple retail employees

It would be interesting to see how union work rules would raise costs and discourage the implementation of new Apple stores. You could help some existing workers and the expense of others, but that is the way unions always work. From CNET:

"The stores have been ranked in the top 50 best places to work by job tracker Glassdoor.com three years running, along with earning other accolades."

Apple stores currently are great places to visit. People are very friendly and anyone can help you out. Could you imagine what union work rules would do to the culture of the place?
