Giving and receiving feedback is one of the hardest skills to get right in the modern workplace. We dig into the subject to find out the best, and worst, ways to hold frank discussions at work. Ed Butler is joined by three expert guests: Joseph Grenny runs a leadership consultancy, VitalSmarts, in Salt Lake City offering advice to business. He also chairs a not for profit organisation called The Other Side Academy, working with former prisoners or homeless people where feedback is instant and honest. Ed also hears from Craig Mawdsley, joint chief strategy officer at the advertising agency AMV and Erin Meyer, a professor of organisational behaviour at Insead business school in Paris. She's the author of The Culture Map, a book looking at the stark differences in national business cultures around the world. (Picture: woman in workplace. Credit: Getty Images)
