I've had to watch a couple episodes of this and it is formula. Model workers are picked out and give their respective sob stories to the boss within 24 hours, the CEO shows up is incompetant and detached from reality and everyone gets a happy ending.
It is not necessarily staged but the cameras certainly tend to bring out personal issues that would not otherwise come out to someone on your first twenty four hours of work and many employees featured have a much stronger dedication to their jobs than most would. It would be a boring episode of course, if the Boss showed up and had history as a retailer with competant employees who just show him the ropes but this show strains the Suspension Of Disbelief
If you go for reality shows, then this is passable compared to some of the garbage they put on air. But it is a reality show all the same with the same awkward narrative set up that will make you groan.
