> Sounds great in theory, unfortunately, this doesn't really work in many situations because you need to be doing the job you were hired for.
I assume that when you are asking for promotion you would have already been doing the job you were hired to do and very well at that. That being the case, if you talk with your manager and they know you want to get promoted and are willing to help you, I see no reason they would be upset about you performing at a higher level.
Of course, every company and even team is different so this doesn't necessarily apply to everyone.
> Really, do you want more money or a better title? A better title doesn't really help at all and in fact can hinder. What you want is more money. Best way to get that is to move to another company.
At a well run company, a better title should come with more money but again, all companies are different.
