Boss asking me to do tasks, stalling on raise and posted the job at 4x my current salary
I sort of slid into doing a new role for my company on top of my normal position. I am interacting with stakeholders now and they're asking my title. Its generic and moderately paid, I am telling them that title. I went to my boss and made a case, he had a million excuses and said to wait, which is fair, theres a lot factors that go into a decision like this. But now I see an "anonymous" company has posted this exact position locally offering 4x my current salary. We are in the middle of nowhere, it's him who posted. When I came to him about a raise and title change, he threw out a suggestion of an extra 200 dollars a month which I did not accept. There is work waiting to be done which I am being grossly underpaid for. I am considering quietly laying off those duties for now.
I'm frustrated and irritated. Help.
And for the record, he has a history of treating people like this, it's not personal.
