Can you really change your behavior at work? What if you believe your approach has served you well in the past and helped you succeed to where you are today? This series of cases features Nicholas Gray, a Norfolk Southern Railroad (NS) executive and his experiences in implementing change from a middle manager position. The A case (UVA-OB-0773) begins with Gray identifying a change effort to build a better relationship with colleagues in other departments at NS. As the story unfolds, Gray's management style and some challenges he faces take shape. In the B case, Gray works through his action plan and the implementation of his change initiative. These cases provide an insight into the challenges of being a change agent at both personal and organizational levels.
