For the vast, overwhelming majority of the workforce that does their job in meatspace, and for their bosses, what this guys says holds no water.
Thank you. As some on here are wont to say, not everyone learns at the same pace. In a similar fashion, not everyone can sit on their ass and do their job from home. If people would take more than three seconds and not have a knee jerk reaction every time this subject comes up, they'd understand the vast amount of people who need to be in the office (for large definitions of office) every day.
Let me know when the gal slinging your pizza for delivery can do that at home. Or the guy who's delivering that pizza to you via whatever overpriced delivery service you're using. The pharmacist getting your drugs prepped for pick up, the delivery driver who delivers the drugs to the pharmacy, the fast food worker grilling your slab of meat, that Starbucks worker making your overpriced mug of coffee-flavored sugar, truck drivers, warehouse workers, farmers, ranchers, landscapers, construction, road workers, chemists, virologists, judges (maybe in between cases), attorneys (again, maybe in between cases), the list goes on. I've only touched on the multitude of people who cannot, under any circumstance, work from home. And that includes some IT folks as well.
As you said, if you're a code warrior or account manager, or a general paper pusher, sure, sit on your ass and get fat at home. For the 75% of the workforce who don't fit into those categories, the office it is. Every day.
