Big Green Brother I found the concept of Wal-Mart employees having personal sustainability plans (PSP's) to be pretty amazing. The employees seem to derive a sense of purpose and satisfaction, while the company benefits from this new found thriftiness of it's workforce. Initially, my reaction was one of surprise that Wal-Mart is making an effort to become more sustainable, but now that I think about it, sustainable behaviors can significantly reduce costs, improve employee moral and generate community goowill. It all makes sense now. If Wal-Mart, with its detestable reputation can pull this off, there is no excuse for our companies! I am going to check out both the ghetto Wal-Mart (even though it's in the suburbs) and the white bread Wal-Mart to see if these behaviors are being exhibited by both stores.
