Case Summary (G.R. No. L-51254)

Applicable Law

The primary legal instrument in question is Presidential Decree No. 851, which mandates that all employers must pay employees earning a basic salary of not more than P1,000 a month a 13th-month pay not later than December 24 each year. The accompanying rules and regulations elaborate on its implementation and exceptions.
