The dock workers' union announced on its Facebook page that no agreement had been reached with the management and added that the strike began at 2pm on Tuesday.
Sveriges Hamnar, or Ports of Sweden – an industry and employers' organization comprising 60 port companies and over 4,000 employees – slammed the move.
According to the employers' organization, around half of container traffic in Sweden passes through the Gothenburg port, operated by APM Terminals (Maersk Group), which is Scandinavia's largest. Only one third of the container traffic will operate during the strike.
The world's second largest truck-maker Volvo said it might disrupt its business.
“We have made short-term plans and if the strike is limited to three days we can maintain production,” Joakim Kenndal, press chief at Volvo Group, told Swedish public broadcaster SVT. “But after three days we don't know,” he added.
