I enjoyed the article as well. I think the article skews a little bit to the positive with the Kellogg case study... saying the workers were all but too happy to scale back to 6 hour days... what I think they neglect to highlight was that they knew the alternative was layoffs, which could have led to even more layoffs, as the plant was such a huge part of the local economy. I believe it was during the Great Depression that this all happened? Although kudos to Kellogg's for even offering that as an option.
What is interesting is, after they were forced into fewer hours, they found that their qualify of life increased, but I don't believe many foresaw that increase.
I wonder, if the offer was made in a different economic climate (such as today), if people would have been willing to take the shorter work week option? Many ERE types likely would, but I don't think the average person would. It would likely need to be legislated in some fashion, either from corporate leadership, or from the government, and I think we are quite far away from that happening at the moment, sadly enough.
