Final answer:
Marcus is employing the leadership managerial function to guide and motivate his employees, indicative of a Theory Y approach, where employees are encouraged to participate actively and be self-motivated towards achieving organizational goals.
Step-by-step explanation:
Since Marcus is responsible for organizational outcomes, Marcus gives guidance to ten other employees using the leadership managerial function, as he motivates them by a number of methods. This scenario reflects the concept of management and organizational structure within the framework of Industrial-Organizational (I-O) psychology.
The leadership style Marcus may use could be related to Douglas McGregor's Theory X and Theory Y. Theory X posits that employees inherently dislike work and must be coerced, controlled, or threatened with punishment to achieve goals.
In contrast, Theory Y suggests that employees may be self-directed and creative if properly motivated. As a leader, Marcus may utilize a style that fits either theory, but his role in motivating employees suggests a more Theory Y approach. By providing guidance and motivation, Marcus is likely to create a work environment that encourages employee participation, considers their suggestions, and inspires them to work towards the organization's goals without the sole incentive of being paid.
