The unforgivable action here is the badmouthing of the workers that they fired, gloating about increased morale. Not even Uber would sink that low. This crap from management shouldn't be tolerated, much less celebrated.
I'm not for or against it, but I imagine being one of those workers it would suck.
Still, I'm all for automating as much as possible, and in the case of workforce reductions, gloating over the fact that things move so much more quickly and accurately.
I do like Elon Musks's attitude toward people wasting time. And this is head and shoulders above what goes on in China, India factory conditions. Not saying no one should whine and bitch and moan about it, but truly, it's not all that bad.
