Things aren't always how they present on the outside, especially when it comes to the inner workings of our most prominent brands. These 21 people decided to share the insider corporate secrets from their former jobs, hopefully giving the rest of us some insight into industries we'd otherwise still be in the dark about. 

Navigating the American health insurance industry might be the most difficult thing our country asks normal citizens to do for themselves. If you've ever had a surprise hospital visit, you'll know the pace at which obscure charges rack themselves up. That random person who just came in to see you? Better make sure they're covered by the same policies everyone else is. But most of the difficulties many people face are built into the system. "Keep escalating and involve your doctor," one person wrote. "Fight for the insurance you paid for," and many of them will eventually give in, as frustrating as it is to do that.
