>I have a good relationship with my manager, That's fine but that isn't what I wanted to emphasize. My point is that if you're at a Big Corporation, both you and your manager are embedded in a bureaucracy. Your manager can't single-handedly wave a wand and get you a raise on his own. He/she has to convince his superiors and Human Resources to get you a raise. You need to imagine what your manager's bullet points would be to argue on your behalf to convince the company to increase your salary. What are your leverage points? E.g. your role in data science work is crucial to release a $200 million product on time in the next 6 months. If you leave, everything falls apart. On the other hand, if you have no leverage and want a raise outside of the annual review cycle and while doing the same work with no promotion... that's a harder sell for your manager.
