In reality she would have sacked half of them without even being in the room and had them escorted out by the same security that protects her. Ain't nobody getting anywhere near her with a guillotine.
She would mumble something about needing to streamline the company's processes to remain competitive. Not to the workers, of course-- To a board of directors who are barely paying attention, other than making sure number goes up.
The workers would just be informed that half of them are no longer employed there.
I was into Ayn Rand in high school and in retrospect I guess I'd say that, given the things I thought were important, I was rational. But certainly my values weren't quite...I dunno...human?
That's why the realistic outcome to this scenario is that she fires half her workforce there by maintaining the same level of production while also slashing labour costs.
I think the comic is supposed to be a lampooning of Ayn Rand's philosophy... Not an accurate model of business considerations within a production based industry.
For the longest time I used to shelve Rand next to Marx on my bookshelf. I've read both at various points (might as well learn the source material if you're going to argue about politics...), but it tickled me as a centrist to annoy their ghosts equally.
