About 2 weeks ago I met with my manager concerning some feedback I was given on a performance review. I have now been with this company 1 year on the nose.
I was informed that I was promoted in title and receiving a raise of about 5.5 percent.
I feigned excitement at this. The review contained some negative feedback which is objectively and provably false. It also has not taken into account my recent (2 months ago) very critical contributions to our release, which took a lot of overtime, and I would argue show me as a very strong developer.
I also don't know if 5.5 percent is a lot. I have no idea where I stand relative to my peers or others who have received promotions. If there's a possibility for more on the table, I don't know it. I know I have grown significantly at this company, and I feel like I'm being lowballed. My company also has a policy against discussing pay/titles with co-workers, so I don't feel safe talking about it with my peers.
All I have is confusion, which is not comforting when it comes to my compensation. I have no idea how they arrived at this figure. I also feel as though I was given no outlet to contest negative feedback.
The core of the question is that I would like to negotiate a higher raise, but completely lack any insight into how the original figure was calculated. Would I appear petty if I brought up these concerns to my manager, or do the members of this community view these types of concerns as valid? If it's the latter, could I also ask for advice about how to approach my manager?
