The new Act on posting of Workers entered into force 1 June 2017. The new Act gives trade unions increased rights for industrial actions. Swedish trade unions shall, in a posting of workers situation, have right to use industrial actions towards employers who are not bound by a Swedish collective bargaining agreement, regardless of what conditions the employer actually apply for the foreign workers. This means that Lex Laval from 2010, prohibiting such actions, is torn up. The new act regarding Posting of Workers also contains new formal rules and regulations increasing the possibilities for supervision of compliance with the law.
