Which of the following best describes the term "job enrichment"?

Job enrichment refers to the practice of enhancing a job by increasing the complexity of tasks and responsibilities associated with it. This approach focuses on adding more depth to a job, encouraging employees to take on more challenging projects, and enabling them to exercise greater control over their work.

By increasing job complexity, job enrichment aims to boost employee engagement and satisfaction. It often leads to a more fulfilling work experience, as employees are provided with opportunities to develop new skills and take on more responsibility, which can contribute to higher motivation and productivity levels.

In contrast, the other options do not accurately capture the essence of job enrichment. Delegating tasks involves assigning tasks to others, which may not necessarily enhance the job itself. Improving working conditions pertains more to the physical or environmental aspects of a job rather than its content. Training techniques focus on developing skills but do not inherently change the job's responsibilities or complexity. Therefore, increasing job complexity is the most accurate way to describe job enrichment.
