Blockade
Trade unions can decide to begin a blockade against a company in order to make the company pay wages according to collective agreements or to exert pressure on the company to sign a collective agreement.
The European Court of Justice decided 11 December 2007 in the so-called Viking case and 18 December 2007 in the Vaxholm or Laval-case that blockades from the trade unions may be illegal when workers act for higher salaries than the minimum salary.
