Switzerland is holding a referendum on proposals to curb immigration, prompting a rare joint campaign by businesses and unions. Opponents warn the initiative could jeopardize decades of trade agreements with the European Union. Concerns center on potential labor shortages in vital sectors of the Swiss economy. The “Ne zu 10 Millionen” (“No to 10 Million”) initiative aims to limit population growth, indirectly restricting immigration. Business leaders and labor representatives argue the changes would harm Switzerland’s economic competitiveness. The outcome of the vote is uncertain, but the debate highlights growing anxieties about immigration levels within the country. The referendum reflects a broader European trend of increased scrutiny of immigration policies.
