Employers found hiring undocumented migrants could face fines of up to R100,000 per worker, Deputy Employment and Labour Minister Jomo Sibiya said.

The deputy minister of Employment and Labour, Jomo Sibiya, says the department plans to impose fines of up to R100,000 per undocumented worker on employers found to be hiring illegal migrants.

The department also plans to recruit 10,000 labour inspectors to strengthen enforcement of South Africa's labour and immigration laws.

The measures follow President Cyril Ramaphosa's announcement on Sunday that the government would increase penalties, including imprisonment, for employers who violate the Immigration Act by employing undocumented foreign nationals.

Ramaphosa addressed the nation amid growing tensions over illegal immigration, recent protests targeting foreign nationals and calls for a nationwide shutdown on June 30 demanding that undocumented migrants leave the country.
