Whispering "Your fly is down!" to someone who needs to know, may be a bit hard, but it shows your concern and helps the person. This book is about how to maximize your "radical candor" with others at work.

Kim Scott talks about how to build effective relationships at your job -- especially with people you manage. They don't need to be fake-friend and they don't need to be coldly inhuman, but if you manage a team, talking with people about personal goals will help the team achieve its goals more efficiently and build a place where people want to bring their best.

While I do Scott naturally favors systematizing personal relationships to an excessive degree, the analytical tool of understanding where you fall on the 2-dimensional "caring personally" vs "challenging directly" axes helps ensure you're expressing concern in the most beneficial way to the most people, while avoiding the common pitfalls of seeing something but not saying anything ("ruinous empathy") or being a jerk without a purpose ("obnoxious aggression"). I like the evidence-based approach she uses in constantly looking for changes in others and yourself, and giving others a chance to address problems they see in anonymous or unthreatening ways.

This is definitely a chart I'm printing out and hanging at my desk so that I can more completely absorb it. There's wisdom and perspective changes to digest here that transcend your typical book on management or leadership. Putting this one on the "to re-read" shelf, so that I can check back again in a couple years to see if I've gotten it.
