The document discusses the emergence of the human relations approach in organizational communication. It summarizes some key studies and theories that influenced this approach, including the Hawthorne Studies which found social factors influence productivity, Maslow's hierarchy of needs theory which proposes humans seek to fulfill lower needs before higher needs, and Herzberg's motivation-hygiene theory distinguishing between motivators and hygiene factors. The human relations approach sees employees as humans with needs rather than cogs, and emphasizes social interaction, individual achievement, and two-way communication both vertical and horizontal.
