Every day, employees make decisions about whether to act like givers or like takers. When they act like givers, they contribute to others without seeking anything in return. They might offer assistance, share knowledge, or make valuable introductions. When they act like takers, they try to get other people to serve their ends while carefully guarding their own expertise and time.
Organizations have a strong interest in fostering giving behavior.
