A worker strike against a paper manufacturer in Europe is causing paper shortages for printers in the United States, an example of the supply chain problems plaguing a world economy that is struggling to leave the pandemic behind.

Thousands of workers at mills operated by UPM-Kymmene in Finland have been on strike since early January, and while there was hope that the matter would be resolved expeditiously, strike action was extended for a third time earlier this month until March 12 unless a deal is agreed upon. As the weeks pass, the situation is getting direr for printers and publishers around the world.
