Daniel Goleman is one of my favorite writers for managers, leaders, and professionals. Watch this video and, if you like the ideas and want to expand them fully, take a look at his book: geni.us/5ziIw
I have not worked with Herb Kelleher, so I cannot tell you. But, why assume he has to be one or the other. It is perfectly possible to be transformational leader AND a servant leader - or to be neither. He is a prominent US business leader, so I wam sure you will fimd plenty of opinions out there. And I'm guessing that, among the commentary, you have seen evindence for both approaches. If that is the case, I suspect he will use both styles of leadership at times, and sometimes both at the same time.
I understand as I said I would like to contact you. I’m very much interested in this topic and have some studies as well. I can give you my e mail address if you are willing to talk about it. Best regards
