One must seriously consider his or her professional trajectory and major milestones. Companies these days don't allow for upward movement unless you're willing to spend a decade playing nice with the right people and consistently over-delivering. On the other hand, changing jobs from company to company likely benefits the employee much more by allowing him or her to enter in to a new role that they are fully qualified for. The same goes for pay, even if its a similar role. The primary goal of a Company is to pay the employee as little as possible in order to get the most out of them fulfilling their duties in the role that they were hired to fill. Having the boat rocked by folks changing roles (upward movement) or increasing salaries is something that each Company tries hard to avoid.
