"In 2005, Walmart faced outcry over a leaked internal memo that proposed cutting soaring health costs by, among other things, requiring that all jobs include some physical activity."

Is this Walmart reorganizing for a better customer experience, is this Walmart cutting costs to help fight Amazon, or is this Walmart cutting costs to boost executive bonuses?
