A The best way to request a salary increase is to think like your boss. Know what bottom-line factors your boss must consider, such as pressures from above to squeeze and expenses. Then tailor your pitch to fit the boss’s needs.
For example, the facts that you’ve increased sales and that you’re “completely trained” are plusses, but your boss probably expects you to be trained in a year, and the very function of your job may be to increase sales.
Instead, focus on how you’ve earned your employer, say, more than triple your salary by signing up long-term orders, or how by taking on 25 percent more responsibility you’ve saved the company, say, $10,000 a year in hiring a part-timer.
Translate your accomplishments into dollars. That’ll make your boss realize what a great return on investment you bring to the company. And that’ll make it easier to justify giving you a raise.
