Spin and lack of transparency from those heading our organisations is a frequent criticism. Here are two books that cut through the obfuscation to bring clarity to leadership communication. Chairman of Bell Pottinger Kevin Murray interviewed 60 leading chief executives for The Language of Leaders to show how leaders can achieve great results when communicating transparently. In Talk Normal: Stop the Business Speak, Jargon and Waffle, journalist Tim Phillips steers a path to better communication while giving some hilarious examples of the worst excesses of management speak at work. The session is chaired by John Smythe, chairman of Engage for Change and author of The CEO: Chief Engagement Officer. The session is part of a series on leadership at the festival.
