This document discusses the case of Rob Parson, a banker at Morgan Stanley who is being considered for promotion to Managing Director. While Parson is a top performer who has significantly increased revenues, his individualistic work style and disrespectful behavior towards colleagues does not align with Morgan Stanley's culture. Paul Nasr, who recruited Parson, wants to promote him but others argue this could reward poor behavior and hurt company culture. A 360-degree performance review was implemented, finding that while Parson excels in professional and sales skills, he is weak in teamwork and cultural fit. The summary considers whether Parson should be promoted or given feedback to improve first.
