I am an entry level developer, I and a senior colleague are working on a project. We are part of a much larger team (30 people) that are working on other projects.
I have been asked by my manager to give the whole team a session on the project I am working on to gain some visibility.
I've spent time and effort to make a presentation on my own and now my colleague wants also to pitch into the session. Now I am not sure what is the right way to deal with this situation.
On one hand I feel I should NOT let him in, as I have done all the work getting the presentation ready. But, I do not want to spoil the relationship with a senior colleague who is otherwise helpful. Another perspective is to let him join as one should be a team-player. But here I feel, he too should have helped with the presentation rather than just present my work.
I just don't know how to deal with this. I am worried that if I allow him to help present then I will not get the visibility I need to grow in my team and career. How does one manoeuvre through such situations?
