I have been working at a large company for about a year now. In the first 4 months I interviewed for a different position at the request of my GM and was hired onto a new department essentially getting a 45% pay raise and moved into a new position where they needed someone with my skill set. I ended up teaching myself Python Programming and now use it to improve workflow and accuracy of results. Because of this I have been assigned to a new team (lateral move) and been given a bigger workload to assist with systems improvement efforts. The catch is I am also keeping my old assignments as well so now I am assigned 2 times the work if not more and been told there is no pay raise involved.
Would it make sense to request a pay raise? It just seams like I am being taken advantage of here by moving me into an "IT" like role but still getting the analyst level pay already had in an easier position.
I was told there is no pay raise for this move but I just don't think that is fair of them to ask me to take on over 2x my current workload and not even offer me a reasonable or any compensation.
Is this a situation where I can request more pay or should I just leave it alone?
Update:
There seams to be some confusion as to why I would expect to see a raise in this situation so I want to clarify my background. Keep in mind I have over 15 years of experience as 'IT' and over 10 years of large scale networking and system administration for said large scale networks. They are moving me from an entry level analyst position into a system development position that requires at least 8 years of experience or a 4 year degree and 4 years of experience but are only continuing to pay me at the entry level from my current position in the company.
