Last year your employer gave you a bunch of money- what did you do for it? If you cannot clearly answer this question, you are vulnerable. In today's competitive market it is imperative to create value for your employer. Employers have problems- executives are hired to solve these problems. You must be able to clearly demonstrate a ROI on your salary- otherwise you are simply unnecessary overhead. If you cannot measure improvement in profit, sales, quality, customer satisfaction, efficiency, or cost reduction from a year ago I guarantee your employer is wondering if they are getting commensurate value with the money they are giving you.
How do you create value for your employer? First, make certain you completely understand your boss's goals- they are your goals. Second, make sure these goals are quantifiable. Third, achieve those goals. If you rinse and repeat this process year after year you will continue to create value for your employer. In turn your employer will keep giving you fistfuls of cash.
