I have recently had several encounters where colleagues resign because they think their careers have reached a dead end, or have hit a glass ceiling. Some have invested more than 5 years with the company and yet they feel like there is no way up the pay scale or the corporate ladder. So they tender their resignation without speaking to their manager. You might be in a similar situation and are now seeking alternate employment. Whilst it is good to know your value in the marketplace, try speaking to your superior about your thoughts and concerns. They have a duty to you and to the company and as long as you have been positively contributing to the team, it is likely the company or supervisor will either recommend a pay adjustment or a promotion that is long overdue. I mean hey, what’s the worst that could possibly happen? You leaving?
