Hi,
After graduating, I applied for a certain Masters course to allow me to specialise within a certain field of work. A job opportunity came up in a similar field however, so I thought it would be ideal to gain some experience/money and ideally not have to undertake postgrad study. Consequently I told my manager in the interview that I wouldn't have to undertake a Masters if I successfully got the job, since it wouldn't be necessary anymore.
However during my time in the role, it became apparent that whilst the job has been enjoyable with a good salary, I didn't see much opportunity to progress and learn, and ultimately would much prefer to specialise in the field that I had initially applied for. As a result I reapplied to the original Msc to which I have been accepted and also granted a scholarship.
The tough part now is having to explain the decision to my manager who won't have seen it coming since they've been under the impression that I abandoned the postgraduate pursuit. To make matters worse, I have never brought up my reverted intentions in our meetings since I didn't think it would help in the matter.
Please could anyone offer advice as to how I can best approach this dreaded meeting in which I will declare my resignation? I feel like I will be betraying my manager in a way.
