Abstract
We conduct a randomized controlled trial (RCT) to evaluate the impact of on-the-job soft skills training for supervisors on line productivity, worker attendance, and psychological well-being in five garment factories in Bangladesh. Line supervisors and chiefs are randomly selected to receive either ten sessions of cognitive behavioral therapy featuring effective communication and stress management techniques; ten health information sessions (active control intervention), or no intervention (pure control group). We measure stress levels using biomarkers (hair cortisol) and self-reported data. We also measure on-the-job productivity, income, absenteeism, and hours of work.

Experimental Details
Interventions
Intervention(s)
Each worker will receive either 10 sessions of Cognitive-Behavioral Therapy (1 hour per week for 10 weeks) or the same amount of a placebo intervention. CBT is one of the most extensively researched forms of psychotherapy and is currently considered the gold standard for treating anxiety disorders, stress and depression (Farrand and Woodford, 2013; Hofmann and Smits 2008, Butler at al., 2006). CBT is intended to build life skills by modifying thinking and behavioral patterns that maintain worrying and stress. It teaches individuals adequate coping strategies through standardized cognitive exercises (handouts and worksheets) and behavioral exercises (e.g. muscular relaxation, mindfulness meditation, etc.).
