I have worked in P&G for 6 years now. I got promoted recently and as such I became boss of a few people who were my peers/friends for about 4 years. This puts me in a very delicate situation. I don't want to boss them too much and loose their friendship or appear arrogant. At the same time, I don't want them to be casual in their approach to me. Any suggestions from my friends here as to how I set the boundaries?
