Swiss voters have overwhelmingly rejected a proposal that would have introduced the world's highest minimum wage, early results from a referendum indicate.
About 77 per cent of voters cast ballots on Sunday against the measure that would have set an hourly minimum wage of 22 francs, Swiss broadcaster SRF projected.
A wage at that rate would have equated to $28.55 in New Zealand dollars, just over double the current New Zealand adult minimum wage of $14.25 an hour.
The referendum was launched by left-wing parties and trade unions, which argued that such a salary was necessary for making a decent living in Switzerland, where the cost of living is among the highest in the world.
The government and employers associations had campaigned against the plan, warning that companies would shift operations to neighbouring countries and Switzerland's important tourism sector would suffer.
