My dept is being restructured, and as part of this my boss is stepping down from her current role into the level below (level with my peers, her choice). I will still report to her, so the result is effectively a demotion for me as she bumps me a level down, and also a significant reduction in my opportunities for development since she will own all the projects. I'm not happy at all about this, everyone else at my level and above is advantaged by the change, I feel seriously disadvantaged. Is there anything I can do?
