Abstract
The incidence of workplace injury is high in manufacturing in developing countries. In this project, we focus on the impact of intensive training and information on decent work environment among workers and firms. We partner with BRAC, which also collaborates with different trade associations, to understand and evaluate the workplace safety and awareness in the light engineering (LE) sector in Bangladesh. In order to understand the causal effects of information and training on the health and safety at the firm level, we randomly assign firms in LE sectors into two treatment arms: T1: Managers/owners of firms receive intensive training on occupational health and safety (OHS). T2: OHS + business training and financial linkages, C: the firms in the control group receive no training. We examine a range of outcomes related to workers’ safety and health issues, working environment and safety standards of firm, cost, business growth, investment and profitability.

Experimental Details
Interventions
Intervention(s)
Intervention at the firm level:
There were 2451 firms selected for randomization at the beginning from 1356 market places in 79 sub-districts from 20 districts. The randomization was carried out at the market level such that all firms in a market were either considered as treatment or control groups. There were 650 markets selected for treatment and 706 markets for control groups. In terms of the number of firms, they comprised 1172 firms in treatment groups and 1279 firms in control groups.

The treatment firms are further randomly divided into two treatment arms T1 and T2. T1 has 597 firms and T2 has 575 firms

Intervention T1: The owners/managers of the firms in treatment group T1 receive intensive training on occupational health and safety. A training module was developed with videos demonstrating safety awareness of firms and workers. The managers/owners receive a week-long training on the module considering the hazardous working environment of the firms.

Intervention T2: Mangers/owners of the firms in this arm receive training on business management and was offered to provide financial linkages in addition to the training on decent work received by the T1 firms. .

Primary Outcomes
Primary Outcomes (end points)
Our primary outcomes of interest are owners/managers’ knowledge and workers’ perception and experience of working environment of the firms. We will also examine changes and practices of firms in improving the working conditions, the incidence of accidents, revenue, sales, profits, number of employees, and other potential outcomes. For measuring decent and safe work environment, our primary outcomes of interest are ventilation system, cleanliness of the workplace, use of safety equipment such as gloves, helmets etc., access to fire extinguisher, access to clean drinking water, clean toilets, timely wage payment, employment agreement, weekly off days, etc. Owners/managers’ knowledge of OSH includes knowing the protocols in case of accidents such as short-circuit, fire, injury etc.
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
We will explore the mechanisms through which the intervention may change the behaviour of owners/managers. We examine owners/managers’ attitude towards risk, general health risk and safety concern, concern about the environment and others (altruism), self-esteem, resilience, competitiveness, entrepreneurial aspirations, and cognitive abilities.
A detail framework for measuring decent work has been provided by the ILO (Anker, Chernyshev, Egger, Mehran, & Ritter, 2002). We follow it in creating our measure of decent work environment. Appendix A provides a detailed description of the various outcome variables.
Secondary Outcomes (explanation)
Experimental Design
Experimental Design
This is a clustered randomized controlled trials. Each market is treated as single cluster. Firms were randomly assigned in different groups across different markets (clusters)
