Untreated mental disorders can result in decreased productivity and income, increased workplace accidents, and higher staff turnover rates.

Managers can lead by becoming a Chief Mental Health Officer who educates themselves, builds a supportive culture, reduces stressors, identifies at-risk employees, and provides appropriate assistance and accommodations.
