It's an interesting experimental outcome, but I wonder to what extent the results are impacted by the type of work being done. From the TEDx talk, the company, C-Trip, was actually based in Shanghai. It's a travel agency. It's not mentioned, but if the employees' salary has a variable component and the more they sell the more they earn, then eliminating their commute and giving them an extra 1-2 hours per day to sell travel services, and thereby earn more money, will certainly increase their productivity. I would be interested in knowing if that is the case for these workers. What if the workers were instead, say, an AP/AR department at a fortune 500 company? Would they see the same increase in productivity? The same decrease in turnover and absenteeism? I am not arguing that they wouldn't, only that I'd expect different types of work to have different degrees of improvement.
