What really happens behind the scenes on CBS's 'Undercover Boss'

CBS's show Undercover Boss, in which CEOs secretly work alongside low-level employees to find out what conditions are really like at their businesses, is one of the biggest smashes of the past TV season. It premiered to nearly 39 million viewers right after this year's Super Bowl and continued with strong Sunday night ratings. The most successful post-Super Bowl episode, with 16.72 million viewers, followed Joel Manby of Herschend Family Entertainment as he supervised operations at Silver Dollar City theme park in Branson, Missouri.

Is this show for real, or is it faked?
