This article will explain how a series of educator strikes in 2022 in Ghana led to increased awareness of and calls for tax justice and debt relief from a growing movement of public sector workers and civil society organisations. We chart how the issues and demands of teacher organisations and other public sector workers shifted and increased over time, bringing in a new public imaginary to critique IMF driven austerity policies, build and link to global campaigns around debt relief, and signal new possibilities for generating more stable domestic public sector tax revenues. We examine the evolving strategies of growing educator strikes and show how unions are joining together with other civil society and advocacy groups to challenge fiscal austerity and government policies that affect not only their schools and classrooms but their lives and livelihoods. This case describing what Ghanaian teacher unions are doing to organise members to learn about and challenge austerity policies highlights the importance of public sector workers' knowledge, understanding and engaging governmental macro-economic policies and offering alternative solutions.
