In the context of staff recruitment, why is a job designed to include a variety of duties important?

A job designed to include a variety of duties is important primarily because it helps to retain employee interest. When employees are engaged in a diverse range of tasks, they are less likely to experience monotony and boredom, which can lead to dissatisfaction and decreased motivation. Variety in job responsibilities allows employees to utilize different skills and learn new ones, keeping them challenged and stimulated. This increased engagement can lead to higher job satisfaction, improved productivity, and lower turnover rates, as employees feel more invested in their work and continue to find value in their roles.

The other options, while they may have some relevance in the broader context of job design or organizational practices, do not pinpoint the key reason behind the importance of job variety in relation to employee interest and engagement.
