Associate professor of Organisational Behaviour at INSEAD business school, Jennifer Petriglieri has spent over a decade researching how people’s close relationships shape who they become professionally and personally. Her new book Couples That Work looks at how dual-career couples can thrive in love and work. We talk to her about the common mistakes that we can fall into as we progress our careers in tandem at different stages of life and the key questions and conversations to have to ensure that we successfully negotiate our personal and professional lives together.
