Hmmm. Is this true? Seems like the ideal way to get a disgruntled front line... You're in a service industry, making 30k a year - 15/hour as a cashier (regardless if you're getting any extra benefits) and your direct superior makes 160k?

I don't know, but I can't imagine a scenario where people don't get pissed-off with such a massive difference for two jobs that are performed on the same location, imply interactions with the same people and are only one command-chain level apart.
