I'm currently working in a small company and I really enjoy the work I'm doing and the people I work with, as well as with the boss himself, with whom I work closely. I do good work and my boss is happy with my performance.
I was recently approached by a recruiter enquiring if I'd be intersted in considering a position at another company. I wasn't really interested in leaving my current position, but I agreed to an interview out of curiosity. The new company is much bigger and appears to be more stuffy than my current position, so considering I don't want to move, I'll probably turn it down. However, the new company is offering substantially more than I'm making in my current position. I would consider leaving just for that.
My question is, considering I don't want to move is there a good way to approach this with my boss? I'd like him to know that the market is offering a lot more than what he is but I don't want to leave. How can I approach my boss to ask for more money showing how much I would like to be paid? I don't want to taint the relationship with my boss because 1) he's my boss and that would be bad, and 2) I work so closely with him.
