An MBA graduate from London Business School recently joined my team. To the annoyance of all other team members, he is living up to the MBA acronym, Mighty Big Attitude. He assumes he is on a fast track to senior management, name-drops his MBA theories, and is reluctant to do tasks he considers beneath him. How should I approach him about his manner in the work environment? I have no doubt he is a skilled worker but his cocksure demeanour and lack of team awareness must surely be addressed?
