According to Erik Helgeson, the association's vice chairman, it is about a total shutdown of work – if the collective bargaining negotiations have not reached further by then.
We are issuing a strike notice on May 21, between 12 and 18 in all Swedish ports, he says at a press conference.
This is an initial industrial action to achieve constructive talks.
Among the demands from the association is a limitation on how many of the employees who should be employed through staffing agencies.
Against the background that Erik Helgeson was previously dismissed from his position at the Port of Gothenburg, the Port Workers' Association also wants to see a strengthened negotiating obligation and better protection for elected representatives.
