Final answer:
Editors working to ensure authors meet a deadline operate within the operations functional area. Organizational psychology is the branch of I-O psychology that measures job satisfaction.
Step-by-step explanation:
When editors ensure authors meet a deadline, they are predominately working in the operations functional area. Operations is concerned with the day-to-day activities that contribute to the production of goods and services of an organization. In the context of media, this includes the management and oversight of the content creation processes, such as assigning stories, editing content, and managing timelines to ensure that the publication produces a high-quality product in a timely manner.
To answer the second question, the area of Industrial-Organizational (I-O) psychology that measures job satisfaction is organizational psychology. While industrial psychology focuses on understanding the best ways to match individuals to specific job roles and evaluating job performance, organizational psychology is concerned with the study of workplace behavior and how to motivate and retain employees, thereby directly engaging with concepts like job satisfaction.
