Swiss citizens head to the polls on June 14 to vote on whether the country's population should be limited to 10 million, in a referendum some compare to a "Swiss Brexit" and that many businesses fear could hurt the economy if approved.
Supporters of the cap, championed by the right-wing Swiss People's Party (SVP), say the expanding population is testing local infrastructure, roads and public transport to the limits, as well as driving up rents and crime.
Companies and employers, however, worry a "yes" vote would limit Switzerland's access to skilled labor and damage relations with the European Union, its biggest export market.
"As a Swiss citizen, it concerns me very much for the future of our country and its prosperity," said Martin von Moos, CEO of luxury hotels Belvoir in Ruschlikon and Sedartis in Thalwil, near Zurich.
"If we lost all of our foreign staff, the hotel simply wouldn't function," he said, noting nearly half of his 115 staff came from outside Switzerland.
