Trust is not easy to quantify. But without it, many things in life become impossible. Humanitarian work is no exception. Jessie Thomson, IFRC’s head of delegation in Türkiye, shares what she’s learned about building trust, including some essential, concrete behaviours that build trust among partners, the public and work teams. When trust is present, she says, people are more effective, innovative and less afraid to take on more ambitious goals. One example of trust in action, she says, was the massive and rapid 2023 earthquake response, led by the Turkish Red Crescent with support from the IFRC network.
