Campaigners announced on Thursday that they collected just over 55,200 signatures over the past three months to challenge a decision by parliament in favour of paternity leave from last September.
The committeeExternal link led by a parliamentarian from the right-wing Swiss People’s Party said it was confident it could force a referendum despite recent doubts.
Opponents argue the benefits are too expensive for employers and the state should not have to be involved in private family matters.
The cost of the scheme is estimated at CHF229 million ($236 million) annually.
The two-week paternity leave agreed by parliament is a counter-proposal to a people’s initiative by trade unions and other civil society groups, which called for a four-week statutory paternity leave.
There are also plans afoot, supported by left-wing parties in parliament, for an even longer parental leave to be shared between the mother and the father of a newborn.
Currently, in offering zero days of statutory paid paternity leave, Switzerland is bottom of the table of industrialised countries along with the United States, Germany and Japan.
A 14-week maternity leave was introduced in Switzerland 15 years ago following a nationwide vote.
