A while back someone posted a link to Walmart aviation which I watched. The thing that struck me as odd was the number of security cameras housed in the ceiling of the office where the schedulers worked. I can understand a couple of cameras looking at the doors or the cash drawer but this looked like a LOT. I guess we can't have the employees looking at emails or taking personal calls while at work
