Before the negotiation starts, be prepared to leave the job if the company offers you a meager raise or no raise at all. Developing a "walk-away point" may be challenging, but knowing when to do it is an essential step in your career. You could turn down a low offer based on financial need, market value, or simply because you are aware of your worth and refuse to remain in a place that is unwilling to reward you with what you deserve.
