Apparently this is 9% or 15% of the employees (there's some discrepancy). So not "only".
I agree that it's on management if employees are only working 2 hours a day and getting paid 8... but one of the things management can do about it is lay off the excess employees. Either they aren't needed or they need some different people.
I've been on the receiving end of that before, it's infuriating.
Based on the excuse he gave to Forbes I’d bet you’re right. I’d especially believe some kind of internal inefficiency – e.g. having everyone need to have sign-offs by someone in an understaffed role – or simply having inefficient internal processes meaning that what he thinks is a 2 hour task actually taking much longer.
Another possibility would be something like having over-hired either due to misjudgment or to look like a bigger business to investors and then blaming the workers for not having enough work to do. I remember seeing that from the dotcom era, along with people who were very proud of 7 figure Oracle clusters handling hundreds of transactions per day. Senior management was so focused on IPO riches that they allowed if not actually encouraged it.
What are you talking about? Entire countries have been doing it for decades before ending up bankrupt.
A similar story revolves around the American South. Southerners used to be stereotyped as lazy until indoor plumbing & antiparasitic drugs eradicated hookworm and air conditioning mitigated the climate’s impact on office productivity. “Lazy” was, well, a lazy way to characterize a more complicated situation.
