I've been told that I will be receiving a title change in a few months which entails a lot more responsibility. The promotion is technically a management level position, while I'm currently not a manager of anyone. There was no mention of a salary increase that will go along with the title change (which is not to say that there won't be one). Though, I know that my sister went through receiving a title change with added responsibility and they never gave her an increase for it. I'd like to make sure that it doesn't happen to me, just in case.
So, my question is - How and when should I ask my boss if my title change comes with a salary increase?
