I've accidentally found out that the other person in my organisation who does the same job as me is being paid significantly more than me.
I opened a document in a shared folder that shows her salary. It shouldn't have been available for me to view, but I was looking for something else and I saw it.
Our job title is the same and we do the same job day to day but on different projects. She does have some skills and experience that I don't, but I also have some skills and experience that she doesn't.
I don't really know how to approach this with my line manager. Does anyone have any suggestions? What I do know is I'm beginning to feel like my contribution doesn't have any value and it's really affecting my motivation.
