You spend your life trying to get to the top in business. Then, when you do, you get driven to meetings, enjoy a wonderful expense account and all the perks of the job. But how do you stay in touch with the people on the shop floor? Evan Davis asks his top-rung guests to divulge how much time they spend with those on the bottom rung, and how important they think it is for the success of their business. Evan's guests are Carolyn McCall, chief executive of the Guardian Media Group, Patrick Dempsey of Whitbread Hotels and Restaurants and Peter Taylor, managing partner of leading private equity group Duke Street.
