[Excerpt] Almost 40 years after publishing A Behavioral Theory of Labor Negotiations in 1965, the fields of negotiations and organizational behavior experienced an “affective revolution” (Barsade, Brief and Spataro 2003). Although Walton and McKersie could not have predicted the widespread academic and public interest in emotion and emotional intelligence, they foreshadowed this affect-laden direction in the section of their book on attitudinal structuring, which identified the dimension of friendliness-hostility as a critical aspect of the relationship between negotiating parties in the workplace and other settings.
