So, very nicely, my manager has created a senior editor role for me, basically as I've been there a whole and she wanted me to have somewhere to 'go' from it, and it starts tomorrow. At the mo, the extra responsibilities are fairly minor, mostly in terms on mentoring a new editor and shadowing my manager a bit for stuff so I can take over when she's not around. I'm not sure what to do when changing my CV/LinkedIn to reflect this, given the role is effectively not changed much. Do I just change my job title? Put 'Editor March 2013-June 18', 'Senior editor July 18 -' ? and adapt slightly my job description/achievements below That's easily done on CV, I suppose, harder on LinkedIn without making it look like a whole new job, but maybe I can just describe my Editor role very briefly and use the longer version under Senior Editor?
