<human>: Condense the text into a few key points

Hello!

I am currently employed in a middle management white collar position. I was promoted into the position from entry level within the company. 

Before throwing my name in the hat for the management, I was open with my employer regarding my plans to go back to school for an unrelated major. When interviewing for the management position, I was open that the promotion would not halt my school plans.

My employer has been supportive of my continued education. My boss is flexible & willing to work around my class schedule. 

This summer I will be eligible to intern in the field I'm going to school for. I will not be able to continue working my full-time job & intern & still complete my classes.  

My company has done right by me, so how do I go about handling this? Should I wait to even discuss it with my boss until I'm accepted into the internship program? 

Sorry if this is convoluted.  Any advice is appreciated.
