This is the best book you will ever buy for human resources management. I'm currently studying for my BA in business and this book has been useful every time. It can look a little intimidating by the sheer size of it but he writing is quite big and easy to read and the content is everything you can need. It touches on many subjects and is helpful for other subjects too. Amazing prices as well as in second hand book shop or new in a store can be astronomical. I bought mine second hand and the quality is brand new.
