I have been working at my company for the past two years and have so far received fair and positive appraisal reports. I’ve met most of my boss’s expectations with regards to general and individual KPIs and feel I am an asset to the company. Although I think my superiors are happy with my performance, there have been minimal rewards for my continued dedication. I would like to request a salary increase, but am concerned I will adversely affect my relationship with senior management. How do I best approach a request for an increase, while maintaining good rapport?
