“Hundreds of thousands of British teachers, air traffic controllers, customs officers and other public sector workers went on strike Thursday, causing potential chaos for schoolchildren and travelers.
Workers are marching in many British cities, including London, where thousands of strikers marched peacefully in the center of the city, their route taking them near the prime minister’s office at 10 Downing Street.”
