Teachers have taken to the streets in numerous states this year, staging an unprecedented series of strikes starting in West Virginia and moving west as they demanded higher pay and more money for public schools. What’s more, hundreds of teachers have decided to run for office at the local, state and federal levels, tired of policymakers who don’t have a clue about what educators do or the difficulties their students face.

But it’s not just in the United States where teachers are demanding more pay or more resources for schools. They’re doing it, too, in Argentina, Britain, Chile, India, the Philippines and Venezuela. In Yemen, many teachers haven’t been paid for two years.

Here are pictures that tell the story of teacher discontent in various countries or that chronicle troubles teachers face:
