ACT Teachers Party-list Rep. France Castro urged colleagues at the House of Representatives to conduct an investigation on the recent disappearance of one of its coordinators and a development worker.

Castro said the group is deeply concerned about the disappearance of ACT Region 7 Union Volunteer Coordinator Dyan Gumanao and development worker Armand Dayoha.

The whereabouts of Gumanao and Dayoha were unknown since January 10.

Castro described Gumanao as a tireless advocate for education and teachers’ rights and welfare.

She added Gumanao’s disappearance is particularly troubling given the reports of surveillance by suspected state forces in recent months.

“We believe that Dyan’s disappearance is part of the ongoing state attacks on unionists and union rights, and we demand that the state forces surface Dyan and Armand and bring them back to their families and co-workers,” Castro stressed.

“Congress should investigate their disappearance so as to help in preventing this from happening again,” she added.

The solon also called on the International Labor Organization’s High-Level Tripartite Mission to investigate the case and press the government to take action on their disappearance, as well as the hundreds of other cases of attacks against freedom of association that have occurred under the Marcos regime.
