Corporate Social Responsibility (CSR) is a business model by which companies make a concerted effort to operate in ways that enhance society and the environment. This includes ethical responsibilities, which involve going beyond legal requirements to do what is right, just, and fair. Providing parental leave benefits that exceed legal mandates is a direct example of a company fulfilling its ethical and social responsibilities to its employees, a key stakeholder group. This action demonstrates a commitment to employee well-being and work-life balance, which are central tenets of the social dimension of CSR.

A. Ethics code: An ethics code is a formal document outlining principles and guidelines for conduct. The action of providing benefits is an application of such principles, not the code itself.

C. Supply chain sustainability: This concept focuses on the environmental and social impacts of a company's supply chain, from sourcing materials to product delivery, not internal employee benefits.

D. Integrity: While the organization is acting with integrity (adherence to moral principles), CSR is the specific business framework that encompasses such voluntary, socially beneficial actions toward stakeholders.

In this foundational model, "Ethical Responsibilities" (p. 41) are defined as activities and practices expected by society but not codified into law, which includes providing a higher level of benefits than legally required.

This courseware defines CSR as actions that appear to further some social good, beyond the interests of the firm and that which is required by law. Providing enhanced employee benefits fits this definition.

This article defines CSR as "actions that appear to further some social good, beyond the interests of the firm and that which is required by law" (p. 117), directly aligning with the scenario. https://doi.org/10.5465/amr.2001.4011987
