The document discusses socialization and assimilation within organizations. It outlines three stages of assimilation: 1) the anticipatory stage where a new member forms expectations before joining, 2) the encounter stage where the new member learns organizational norms and requirements, and 3) the metamorphosis stage where the new member masters requirements and adjusts to the organization. The document also discusses how modern technology like social media has influenced the anticipatory stage by allowing new members to research organizations online before joining.
