If the company you work for is raking in 1000 a month
and has to pay out 900 a month for expenses, why would employees scream to make more in wages? Wouldn't they rather try to find ways to make the company more productive, rather than aid in its collapse?
From what I've read, Hostess wasn't doing that great in profits, and the union and union dupes should have known that, and realized what would happen if they kept demanding more.
