So in the short term, the company benefited, yeah? They got more work out of the same people than they would have if they didn't apply the pressure.
Reminds me of an old boss I had who would flat-out say that to get a project done we would "hire someone and burn them out" - he planned to only get six months of useful work out of someone, and if they were stupid enough to stick around for high stress and low pay, that's just a benefit to the company.
(I didn't last very long there either)
