More than 560 dockworkers at the Port of Liverpool, one of Britain’s largest container docks, will go on strike from Sept. 19 to Oct. 3 over pay, the Unite union said on Friday, adding to a summer of industrial unrest caused by soaring inflation.

“Workers across the country are sick to death of being told to take a hit on their wages and living standards,” Unite general secretary Sharon Graham said in a statement, urging the the Mersey Docks and Harbour Company to table a good offer.

The planned Liverpool strike follows an eight-day walkout last month by workers at Felixstowe, Britain’s largest container port, which clogged supply lines but fell short of causing widespread disruption in an industry already facing supply chain issues.
