Which legal act was created specifically to protect overseas workers?

The legal act created specifically to protect overseas workers is the Overseas Workers Welfare Administration (OWWA) Act, also known as RA 10801. This legislation was established to ensure the welfare of overseas Filipino workers (OFWs) and provide various support mechanisms such as legal assistance, welfare services, and reintegration programs upon their return to the Philippines. It aims to safeguard the rights and wellbeing of Filipinos working abroad, addressing their unique challenges and vulnerabilities.

The other options do not serve the same purpose. The PESO Act of 1999 focuses on establishing a public employment service office to improve employment services, while RA 10706 relates to the establishment of a government corporation for the welfare of Muslim Filipinos. Finally, RA 6657 is the Comprehensive Agrarian Reform Law, which deals with land reform and the agrarian sector, making it unrelated to the protection of overseas workers. Thus, the focus of RA 10801 on overseas workers distinctly sets it apart as the correct answer.
