If your only options are "work here" and "die of starvation", then I'm not sure you can really call it a decision at all. Frequently the people doing the work can not, in fact, make any decisions. The guy who owns the factory, on the other hand, will make sure his thugs beat up anyone who brings up fire safety or asks for better working conditions. If that's not slavery, then what is?
