I am not a person who likes to negotiate. I like everything to be on the table so I can make a decision and get it over with. But here is something Roger Dawson says in this book. Suppose you are buying a used car with an $8,000 asking price. You are prepared to pay $6,000. You go to look at the car, test drive it and everything seems fine, so you make the first offer of $5,000, less then your reservation price. "I'll take it" they say. Happy? Probably not. In many situations you are expected to negotiate. In a case like this you are probably thinking that a. "I could have gotten a lower price" and b. "There's something wrong with this car." The same goes for salary negotiation. Most employers expect you to negotiate your salary, and if you don't they're going to think there's something you're not telling them. So if you want to get off on the right foot in your new job, you must negotiate!
This is a fairly short book, about 228 pages of material broken up into 59 chapters, so it's a quick read. There are two secions, one on getting the job and one on negotiating a salary. The second half of the book is great, and tells you many of the common strategies hiring managers will use when they offer you a salary, as well as techniques for overcoming those strategies.
There's not many times when you can earn as high an ROI as when you are negotiating a pay raise for yourself. Spending a few bucks to buy this book and spending a few hours reading it can potentiall get you a few thousand dollars a year in income, so why not read it and try it out?
