Summary

In August 1909, the Swedish Trade Union Confederation (LO) called a general strike to resist wage cuts and lockouts by employers. The strike involved up to 300,000 workers but failed to achieve its goals, ending in September 1909 with employers largely imposing their terms. The outcome weakened the labor movement, with union membership declining sharply.

Background

The depression of 1908 depressed prices and led employers to repeatedly attempt to lower wages and cut back workers’ collective bargaining rights. The Swedish Employers’ Confederation (SAF) launched lockouts in June and July 1909, intensifying conflict with the Swedish Trade Union Confederation (LO). The LO called a general strike on August 4, 1909, aiming to force government mediation and secure an acceptable compromise.

What happened

The LO called a general strike on August 4, 1909, for manufacturing and transportation workers, hoping to model it after the successful 1902 strike for universal suffrage [source: nv-database]. At its peak, 300,000 out of 500,000 workers obeyed the call [source: nv-database]. The LO excluded key sectors such as electricity, water, street sweeping, and animal care workers to maintain liberal support, and railroad and dock workers did not join [source: nv-database]. Typographers joined on August 9, which alienated liberals who saw it as an attack on free speech [source: nv-database]. Unable to gain liberal support and with funds running low, the LO ended the strike on September 4, 1909 [source: nv-database]. After the strike, employers locked out large numbers of workers, and defensive strikes continued; the last lockouts ended in December 1910 [source: nv-database]. The terms agreed were almost identical to those proposed by the SAF before the strike, and the National Labor Federation lost 50 percent of its membership by 1910 [source: nv-database].

Key people & organizations

  • Swedish Trade Union Confederation (LO)
  • Swedish Employers’ Confederation (SAF)
  • Transport
  • typographer union
  • Liberal politicians
  • Conservative Government

Outcome

Verdict: lost.

The strike failed to achieve its demands, as employers largely imposed their terms and the labor movement was weakened. The LO’s cautious strategy, exclusion of critical workers, and inability to secure liberal support contributed to the loss. [source: nv-database]

Lessons

  • A general strike requires broad participation across key economic sectors to be effective.
  • Maintaining unity between union leadership and rank-and-file members is crucial to avoid divergence in goals.
  • Excluding sectors to appease political allies can undermine the strike’s disruptive power.
