Communication letter from the president

April 17, 2020


To My Dear GRET Stakeholders,


Happy Easter!

As we all enter the fifth week since our last general assembly where we communicated with you the devastating impact of COVID-19 on our business operation, I hope and believe that you are all safe and in good spirits.

Sadly, since that time, we’ve all borne witness to how this insidious virus is impacting our families, our communities and our very way of life. What we’re facing is alarming and uncertain, but I am heartened by the moments of triumph in everyday acts of courage, humanity and love. Although these are trying times for us all, I remain optimistic that our business will thrive once again.


For Our CSR

GMI understands that the pulse of the Filipinos beats as one to overcome COVID-19 and its devastating impact. As we all watch the news broadcasts unfold about this unprecedented event, it’ clear that there is a need to assist and bolster healthcare workers and community caregivers who are on the frontlines working to contain this disease. To that end, we have established aids in the urgent fight against the pandemic. Domestically, our company is in a unique position to help by providing food, pre-packed and cooked meals to crisis relief efforts and much-needed supplies like cleaning products, masks, gloves, face shields, goggles for medical and other frontline workers and some left out in our community:


(Mandaluyong City Medical Center, San Felipe Neri Parish, Clarisas Capuchinas Sacramentarias Capuchin Poor Clares of the Blessed Sacrament, Manila City Jail, Mandaluyong City Jail)


It’s that kind of spirit that will sustain us through this crisis.


For Our Customers

Given the unprecedented disruption to our business, our company had to close temporarily. However, we remain committed to ensuring our customers experience flexibility during these challenging times, so we have further extended our skeletal work force to supply necessary assistance to hospitals and clinics which remain open. Please note that this demand is subject to availability of our stocks and available personnel.


For Our Employees

Today, I want to let you know how we’ve focused on supporting our employees to provide with one month salary, compensation and benefits even during the Enhanced Community Quarantine ECQ. I also want to take this chance to thank our employees who actively work even during this moment. Some of you have to walk far and line up check points just to get to the office to report. Once again my sincerest gratitude to our own front liners. As the days unfold, we will continue to monitor and evolve our work requirements and assemble as necessary.


Thank you for all your prayers, rest assure you are all included in ours. As always we consider each one of you a part of our extended family.


We will see you again. Until that day comes, stay well.
