They didn't in the novel, not really. Francisco d'Anconia abandoned his people in Mexico. Midas Mulligan at least made a clean exit. What happened when Ellis Wyatt's oil workers woke up that morning to find their fields aflame and the boss taking a powder is not recorded.
It's definitely an issue. In fiction Rand personalized the whole thing to the point where an attack on Wyatt Oil or Reardon Industries was distilled into an attack on only one man. Taggart Transcontinental's employees are listless no-loads in one part of the book and loyal, armed guardians in another. It's an issue I'm not sure Rand really resolved, one we'll be following chapter by chapter as we go through the book.
Seeing that Bamsy distilled the attack on the GOP and conservatives into an ideological assault on a single radio announcer, something that I think even Rand would have strained at swallowing, that doesn’t sound so far-fetched now.
