The New York Times reports In the far east, the teachers went on strike. In central Russia, it was the employees of a metallurgical plant. In St. Petersburg, autoworkers laid down their tools. And at a remote construction site in Siberia, laborers painted their complaints in gigantic white letters on the roofs of their dormitories. “Dear Putin, V.V.,” the message said. “Four months without pay.” After months of frustration with an economy sagging under the weight of international sanctions and falling energy prices, workers across Russia are starting to protest against unpaid wages and go on strike, in the first nationwide backlash against President Vladimir V. Putin’s economic policies.
