X-rays hang in a tent that is part of a protest camp in Warsaw, Poland, on Tuesday Sept. 21, 2021. Doctors, nurses and other health care workers have been camping out in front of the Polish prime minister's offices for nearly two weeks to protest their working conditions and demand higher wages. Poland has the lowest number of working doctors to its population in the 27-nation European Union, and its nurses are also stretched thin. (AP Photo/Czarek Sokolowski)
