I'm a first-year MS student working as a part-time student researcher in a lab. Earlier this year, I received and accepted an internship offer as it was my top choice and my goal is to work in the industry. However, when I told my research manager about this during a meeting, it was not taken well at all ... nor was it taken well by the research director later on.
My role isn't a contract position and there are no written conditions that you have to be in this role for a set time. The expectations of me being here in the summer were never stated during the hiring process until now when I mentioned the internships.
I guess despite the prestige of the internship, how I gave them a heads-up about the summer role instead of waiting, and how I've taken on so many tasks/overworked myself as an assistant (and will be working harder to get more things done before I leave in the summer), I'm just surprised people are really unhappy with me. I know my team is in the process of hiring summer interns and the only issue I see is them having to spend time training them with equipment, and maybe they thought an internship meant I wouldn't be back in the fall; but I didn't expect this to go horribly even though I said I'd only be gone for three months.
This never happened with my undergraduate research position, so is this common or am I in the wrong? Just trying to get a clearer perspective on things.
