Would you recommend management undergoes a traditional job redesign approach or a job crafting approach?

Suppose a sports injury clinic has three main practitioners. First, there is a general practitioner doctor who does the basic diagnosis of the injury and works with the patient to come up with an overall treatment program. This doctor also prescribes medicine as needed. Then there is a surgeon who specializes in sports injuries. This doctor only does surgery. Finally, there is a physical therapist who helps patients with exercise programs to help them recover. The owner of the clinic though becomes worried that these three practitioners are becoming bored and dissatisfied with their jobs and there is concern they might all leave unless their jobs change. However, given the high degree of training required for each of their specializations management is not sure how to go about making their jobs less monotonous and more rewarding. In general, would you recommend management undergoes a traditional job redesign approach or a job crafting approach? Which specific job redesign strategy or job crafting strategy would you recommend? For example, if you choose job redesign discuss whether you would recommend job rotation, enlargement, enrichment, etc. If you choose job crafting, refer to one of the specific strategies or interventions discussed in Wrzesniewski (2014) or Dik and Duffy (2012).
