Query: Worthwhile Read

Just got off a cross-country trip, where I started/finished this week.It's a great "plane book".In all honesty, wish I had read this some years back at a time when I had a very difficult boss.It's an easy read with some good, practical suggestions.There is also a self-assessment component, something I usually dislike, but here I really got into it and found the "results" sometimes surprising (to me).Even if you don't hate your boss/job, I think it's an interesting read. Also a perfect gift for those friends who are constantly whining about their bosses!I rate it a 4 out of 5 because, at least for me, it got a bit wordy at the end. If you start skim-reading toward the end, it's a def 5!
