Oh, but it is! Just listen to the Jesus-hates-unions posters in this thread. It's okay for a business to run itself in the ground and then turn to their skilled workers and say work for nothing. Nevermind the fact that Hostess could've just hired replacements, except for the fact that they're broke. Nevermind the fact that they would have had trouble finding a skilled workforce to replace the strikers at the rates they wanted to pay.
Half of this country has stepped back into 19th century England where factories could do no wrong. Work when they say you work and take what they say you take.
