This book contains the basic principles that any HR or General Manager (especially in the US) is supposed to know. I have been using this textbook as a guide for my MBA studies.
I found it very useful in that it clearly explains and organizes almost every important topic about HR management. It gives practical clues on the kind of considerations a manager needs to be aware in day-to-day operation.
I used this book to find basic, straightforward ideas about HR principles and how this function is changing in the era of globalization. This way, I could use it to organize my own ideas, and if needed, using the enclosed bibliography, I could go to more specialized books on a particular topic of interest.
