L'enjeu de l'époque
On 25 September 2005, Swiss voters approved with 56.0 % the federal decree extending the Agreement on the Free Movement of Persons (AFMP) to the ten new states that joined the European Union in May 2004 — Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovak Republic, Czech Republic and Slovenia. Turnout reached 54.5 %.
The vote also concerned the revision of the accompanying measures against wage and social dumping, a central element of the political agreement between the governing majority and the unions. The SVP, AUNS and several conservative circles had launched a referendum, brandishing the spectre of a migration wave from Central and Eastern Europe.
The extension took effect on 1 April 2006, with a transitional regime of quotas and labour-market priority until 1 May 2011. This fact sheet compares the key arguments of the 2005 campaign with the facts documented since entry into force.

Worth noting : The extension to ten very heterogeneous states — from Malta (UK-comparable wealth) to Poland's industrial fabric — was presented as a full-scale stress test of free movement. Fears were particularly strong because of the historical wage gap between Switzerland and some new states (notably Poland and the Baltic countries).
Arguments and verdicts
▲ Arguments FOR (Federal Council, governing parties, business, unions) No two-speed Switzerland vis-à-vis the EU « It is unthinkable for Switzerland to refuse Poles or Czechs what it has granted to the fifteen former member states. Refusing means endangering the Bilaterals I as a whole. » — Federal Council, 2005 explanatory booklet ✓ ✓ Argument confirmed The Federal Council and the EU did treat the extension as a direct prolongation of the AFMP. Refusing the protocol would have, under the guillotine clause of Bilaterals I, jeopardised the seven agreements as a whole. This institutional aspect has been regularly confirmed since (notably at the vote of 9 February 2014 on mass immigration, whose implementation was calibrated to preserve the AFMP).

In 2024, net immigration from the EU/EFTA still reached 53,700 persons and contributed to an EU employment rate of 86.8 % in Switzerland. SECO and multiple studies (Avenir Suisse, BAK Economics) have concluded an overall positive impact on GDP per capita.

SECO's annual balance sheets conclude on an overall effectiveness, with a contained rate of wage violations. The unions — who made it a condition — nonetheless report persistent shortcomings: weak sanctions, uneven cantonal monitoring, real wage pressure on cross-border workers in Ticino.

Immigration from the eight Central and Eastern European countries (EU-8) remained moderate, held back by the transitional regime until 2011 and by the attractiveness of other destinations (United Kingdom, Ireland, Germany). The majority of EU immigration in Switzerland still comes from EU-15 (Germany, Italy, France, Portugal). Polish nationals make up a modest share of the EU/EFTA stock in Switzerland.

For similar characteristics, EU/EFTA nationals on average earn wages comparable to Swiss workers. A risk of undercutting is however identified in Ticino for cross-border workers, partly validating the critique but not the announced collapse effect.

Over 2006-2024 it has remained between 2 % and 4.5 % depending on the cycles, among the lowest in Europe. SECO/SRG studies confirm no massive substitution of Swiss workers by EU nationals. The Swiss activity rate has remained high in parallel. Source : SECO, unemployment statistics; FSO, employment statistics |

Conclusion
Twenty years after the extension of free movement to the ten new member states, the factual record largely validates the arguments of the yes camp. The most alarmist predictions of the no camp — massive migration wave, wage collapse, unemployment explosion — did not materialise.
The wage-dumping argument, by contrast, is not totally unfounded: the Ticino cross-border market is under real pressure, and unions rightly point to limits of the FlaM mechanism. But the generalised effect announced did not happen — EU/EFTA nationals on average earn wages comparable to Swiss workers.
Institutionally, the extension stabilised the bilateral path, avoiding triggering the guillotine clause. This is probably the most structuring effect of the decision: Switzerland has docked onto an evolving European system whose contours it continues to debate at every European-policy vote (2014, 2020, 2025).
