I don't imagine we will actually see this change in the way expected. Rather than companies making it so employees can leave on time and still feel secure in their job, I imagine companies will eventually find themselves destroyed by competition that are smart enough to forego having an office at all. Offices are a massive expense, and while they were crucial and profitable in the era of difficult communications, they're now nothing but a source for value destruction, amplified even greater by the tremendously negative impact on cognitive productivity interruptions have. The exact things that made offices valuable in the past, physical proximity of coworkers, are their greatest weakness now.
