Final answer:
The correct answer is option 3) Participative.
Step-by-step explanation:
Workers with an internal locus of control believe they have control over their own actions and the outcomes of those actions. Such individuals are more likely to be intrinsically motivated and may be less responsive to directive leadership when performing tasks, particularly unchallenging ones. Directive leadership involves providing clear instructions, supervision, and a structured environment, which might be unnecessary and even stifling for these workers.
Given the nature of the tasks and the workers' internal motivation, a participative leadership style is generally more suitable, as it allows employees to make contributions to the decision-making process and increases their engagement, despite the simplicity of the tasks at hand. This approach aligns with the characteristics of workers with an internal locus of control, who desire autonomy and involvement in their work. On the other hand, for employees without an internal locus of control or with tasks that are complex and challenging, a more directive or achievement-oriented style might be more effective.
