Jennifer Petriglieri, an assistant professor of organizational behavior at INSEAD, asks company leaders to consider whether they really need to relocate their high-potential employees or make them travel so much. She says moving around is particularly hard on dual-career couples. And if workers can't set boundaries around mobility and flexibility, she argues, firms lose out on talent. Petriglieri is the author of the HBR article “Talent Management and the Dual-Career Couple.”
