Work Rules!
Work Rules! (Lazlo Bock, 2015)
How I stumbled upon it: My boss recommended this as a must-read after moving to the People Team
What it's about: Written by Google's head of People Operations, this was the most relevant book of the three in my actual day-to-day work. Bock provides a blueprint for how a company should treat it's employees, actionable ways that management and employees can better interact, and details initiatives that have (and have not worked) for Google.
What I thought: Bock is witty without being cheesy and this was easily my favorite of the three reads. You don't have to work in tech to appreciate the lessons he imparts.
You can get it here.
