Modern Slavery Statement

At Callsign, we have a zero tolerance to modern slavery and we are committed to ensuring it has no place in our operations. That is why we have implemented and are enforcing a system of checks and controls to ensure modern slavery cannot operate in our business or in any of our supply chains.

Given the markets we operate in, we assess the risk of Callsign becoming engaged in modern slavery to be low but we refuse to be complacent and we conduct risk based assessments when selecting our third-party suppliers that includes key questions on modern slavery.
