Dear Hbr:

Do you have a hard time with older or younger co-workers? Dan and Alison answer your questions with the help of Jennifer Deal, the co-author of “What Millennials Want from Work.” They talk through what to do when you’re struggling with an older colleague, when you’re managing a much older worker, and how to motivate younger employees who seem lax on the job.
