ILC President Ali Yalçın and ILC Secretary-General Hamza Öksüz were unable to attend the event in person but conveyed their messages of solidarity through video addresses.

In his message, President Ali Yalçın emphasized:
“The honorable journey of K-SARBUMUSI over the past seventy years has not only illuminated the struggle of the Indonesian working class but has also inspired the global labor movement. This long-standing commitment reflects the maturity, determination, and resilience of organized labor. K-SARBUMUSI has played a historic role in the struggle for decent work and social justice, both nationally and internationally.
At ILC, under the motto ‘Together for a Just World,’ we draw strength and inspiration from you. Our struggle is not only for today but also for leaving a fairer, more equal, and more humane world to future generations.”

ILC Secretary-General Hamza Öksüz highlighted the importance of unity and solidarity:
“Every individual deserves a life worthy of human dignity. That is why we came together under the ILC family—not only to defend workers’ rights in our own countries and regions but also to advance labor struggles internationally. Through brotherhood, solidarity, and collective effort, we will continue to fight for social justice and elevate the dignity of labor worldwide. There is still much work ahead of us, and we will accomplish it together.”

Speaking at the anniversary event, K-SARBUMUSI President Irham Ali Syaifuddin reflected on the organization’s legacy and its present role:
“Throughout its 70-year journey, Sarbumusi has been more than a trade union—it has been a central force in the political and social consolidation of the labor movement. Today, with its broad-based organization across multiple sectors, it continues to be a significant national actor. Internationally, as a founding and pioneering member of the ILC, Sarbumusi not only strengthens global labor solidarity but also raises its voice in the struggle for peace and humanity, particularly in support of Palestinian freedom.”

K-SARBUMUSI’s seven-decade-long journey of resilience and commitment continues to serve as an inspiration for the entire ILC family.
