‘Most government workers unaware of uniform law’MANILA, Philippines — About half of government employees in the Philippines are unaware that they may be technically violating the law because of the uniforms they wear. Under the amended implementing rules and regulations of the Philippine Tropical Fabrics (PTF) Law, all fabrics used for government uniforms must contain at least five percent natural fibers or silk by weight. “Every employee who doesn’t wear a PTF uniform is technically in violation of the law. Leaño said PTFs cost between P280 and P350 per yard, making them affordable for uniform suppliers. PTRI is now intensifying its information campaign to raise awareness among government employees about the uniform requirements mandated by law.
