I would like to express my general satisfaction in the position I currently hold in right now, but would like to draw your attention to one particular matter that is a bit unsettling.
As you are aware, my list of duties has been recently augmented for my workload. A larger amount of work is being accomplished in the same frame of time. This increase does not bother me at all. On the contrary, I have always considered myself as a hardworking person and I am ready to speed up my pace accordingly. This is a challenge to my abilities that I cheerfully accept.
Having said so, I would like to kindly ask you to acknowledge my efforts and dedication by considering a salary adjustment. Such an amendment will only result in increased enthusiasm to accomplish even more in less time.
