What advice would you give a park manager if he wants to enrich the jobs of his park rangers?

A) Move your people from job to job
B) Give everyone clearer and more detailed instructions
C) Give each employee more tasks at the same level
D) Give employees more decision-making responsibility
E) Let your people go home at noon

Giving employees more decision-making responsibility can help enrich their jobs by allowing them to have more autonomy and control over their work. It can also lead to more innovative and creative solutions to problems. Additionally, it can increase employee engagement and motivation. Moving people from job to job (A), giving clearer instructions (B), and giving more tasks at the same level (C) may provide some variety but may not necessarily enrich the job itself. Letting people go home at noon (E) is not a viable solution for enriching jobs.
