I liked it.

The teary eyed undercover boss was touching.
I still can't help but say "this was just slumming." As with every other type of "slumming," you leave your safe environment to "see what others go through" or even to help, but your experiences are that of someone who is undercover and is going back to your high living.
Only time will tell whether the bosses incorporate changes in their companies after seeing what employees go through on a daily basis. More importantly, will the bosses incorporate changes in their billion dollar companies even if these changes mess with the company's bottom line, atleast initially. Most companies haven't figured out (and don't want to invest in the revelation) that happier and safer employees make for better work and more profit in the long run.
(The Black guy who made cleaning toilets fun was AWESOME.

There are jobs for EVERYONE and I give props to those who make careers out of odd jobs. People say "well, they're losers because they can't get something better!" Uh...that's the natural distribution of life. If everyone could and did get something "better," who would clean sewers and stuff?
