The ONE place, that beats the whole "strength in numbers" is the multi-billion dollar industry, Walmart. If you've ever seen documentations of just Walmart building new places in small towns, destroying a bustling town to a ghost town, you'd know it is in vain.
My store, used to carry fish. HEALTHY fish! Because the petsection-manager, took care of them, and made sure her employees did their job. If they didn't, they were transfered. However it was the shipping company to make them lose money - dead fish arrives - no sales. :/
Although I work there. So darn rights I have a complaint. or two. or five.

Only perk: work there for a year get a bonus. work there for 2 or more years, double that bonus
