MANILA, Philippines: The country's biggest labor alliance called on Congress that it need not tinker with the 1987 Constitution, saying that it is not the key to the long-aspired economic prosperity but the implementation of critical constitutional provisions, which includes the ban on political dynasties.The Nagkaisa Labor Coalition (Nagkaisa) also pointed out establishing a living wage, strengthening job security, protecting workers who organize unions, setting up environmental protections, and other human rights and social justice clauses.'The problem lies not in the Constitution's wording, but in its elite-driven enforcement,' Matula, in a statement, said as it called on Congress for the deferment of its move to amend or revise certain provisions, particularly the economic aspects of the Constitution.'Amending or revising the Constitution now is not what the people need. Hindi ito ang kinakailangan ng sambayanan. Thus, the question we must ask is, who benefits from these changes? Clearly not the common people,' added Matula.The labor coalition also expressed its disappointment with Senate President Juan Miguel Zubiri's apparent support for charter change.
