I won this book in a Goodreads First Reads giveaway, looked forward to reading it, and found it interesting and intriguing. I may go back and up my stars later, to 4 or even 5, but first I want to try this out and see what happens in my particular workplace over time once I start asking the right questions. Inspiring, but could also prove to be a bit too broad and/or vague (it never tackles issues in severely dysfunctional workplaces, which I'd argue are numerous, yet not covered here -- you see teams working together and communicating, but if you work somewhere where teamwork doesn't happen, nor does communication, and making changes is frowned upon unless you're upper management, then what do you do? Read on to find out). A couple of the examples quoted of "difference makers" are people who've made positive light of what many would consider menial jobs; though they may be all the happier for it, and they certainly are benefiting many around them who are thankful for their dedication and willingness to go the extra mile, I think the book glosses over the true lack of power many have to truly influence their jobs in a way that allows them to do more than "feel good about it"; that is, in a way that rewards them in other than spiritual or ethical terms: upward movement in terms of real authority, increased responsibility and challenge, and increased earnings/economic justice. I know one book can't cover all the bases, but I'm not sure those coming to this text from a lower socioeconomic status are going to connect with this work, which paints a sort of rosy picture about work in America by focusing only on the shiny positives.
