Survey: BH staff and time off for professional development NCETA found that although 57 percent of Australian alcohol and other drug workers reported that their organizations provided access to professional development opportunities, 54% of workers indicated that there was no provision for backup to enable workers to attend training. Nearly 70 percent of workers in rural areas reported that backup staffing was not available. How would the American BH worker respond? It might be worthwhile to review your organization’s track record on not only offering professional development time, but helping staff find backup so they can attend trainings.
