I work as part of a 2 person team. colleague and I do identical work. over the last year, she did less and less. I am a workhorse and just cracked on with stuff that needed sorting and felt I do much more but wasn't too bothered. Anyhow, last week I decided to pull the figures from the system and I do about 4 times as much as she does (it's easily quantified, no idea why I didn't raise it before and why manager never raised it. I guess since the work gets done, nobody is checking). colleague is senior to me and earning much more which irks ms hugely given the backseat she has been taken all year
. Would you raise this and if you are a manager, what would you make of it. I worry I look anal an petty.
