"""Lean In"" promotes a cultural norm of assertiveness. It encourages women to assert themselves in the workplace through negotiating their salaries and working conditions, asking for raises and promotions, challenging gender biases, and being more confident in discussions (instead of being overly apologetic or taking a backseat role).
""Lean Out"" focuses on deprioritising traits like assertiveness, physical strength and dominance, and instead promotes the norms of deference, cooperation, considering the needs of others, and empathy."
