Several hundred workers walked out on Cosatu president Sdumo Dlamini as he delivered his Workers' Day speech on the national minimum wage.
According to a Business Day report, workers left the Isaac Wolfson Stadium in Kwazakhele, near Port Elizabeth, as Dlamini delivered his keynote address.
The report said Dlamini was unfazed by the walkout.
According to a report by the African News Agency, carried in The Citizen, Dlamini told the crowd that those who were leaving could do so since the issues he wanted to discuss had already been raised by previous speakers.
Dlamini has been mired in controversy after allegations emerged that he received a R300 000 bribe.
According to City Press, the Hawks are investigating whether convicted child molester Deon Larry paid Dlamini the bribe, as well as whether former president Jacob Zuma was paid R1m to keep Senzeni Zokwana in his Cabinet.
Cosatu was vociferous in its call to remove Zuma as president.
