Which social responsibility indicator includes considerations for working hours?

The correct choice focuses specifically on "Hours of work," which is a key aspect of social responsibility indicators in the context of ethical sourcing. This indicator measures the number of hours employees work and ensures that these hours are compliant with established labor standards. It helps to safeguard workers' rights by preventing excessive working hours that could lead to fatigue, health issues, or adverse impacts on their quality of life.

By monitoring hours of work, companies can ensure that they provide fair labor conditions, adhering to principles of sustainability and ethical treatment of workers. It is essential for promoting a balanced work-life scenario, demonstrating a commitment to social responsibility within the supply chain.

The other choices, while important aspects of social responsibility, do not directly address the specific issue of working hours. For example, worker safety and training pertain to the conditions in which employees operate and their preparedness for those conditions, while access to housing and education address broader social welfare issues, but do not focus solely on the hours worked by employees.
