Q: I am pursuing a position that pays about $10,000 less than the position I am in now, but it is one more in line with my career aspirations. How do I diplomatically discuss salary and responsibilities?
A: In terms of approaching the potential employer about the pay differential, I suggest you look at the benefits of what this new position may offer, and how you may be able to supplement the loss in income through some projects or other work you can pick up.
Most importantly, be honest with them! Explain that you are very interested in the position, and what you are making now; if they want you enough, they may offer you some other financial incentive to join them.
