False. Managers in organizations typically do not perform all the work by themselves. Rather, managers are responsible for planning, organizing, directing, and coordinating the work of others to achieve organizational goals and objectives. They delegate tasks, allocate resources, provide guidance and support, and monitor performance to ensure that work is carried out efficiently and effectively. Managers may also make decisions, solve problems, and oversee operations, but their primary role is to lead and manage a team or department to achieve desired outcomes collectively.
