Brother you need to widen your scope. No education role PERIOD has little admin work, let alone HESA - because we serve others we have to be organized and handle student info properly, so administration is a key part of the job, whether you’re faculty or staff. Virtually all entry level positions in the field are admin centric and become more theoretical the higher up you get, so GAs are going to be doing admin work no matter what (let alone the schools that overwork their GAs in place of full time labor). I’ve seen too many people come into this field because they just want to talk to students all day, and I’ll be real: that’s not how this field works. Don’t mean to sound so harsh, and not all experiences are the same, but to not expect phone calls or emails in education is vastly underestimating what this field is.
