Numsa and Zwelinzima Vavi's rogue union marched through Durban, competing with Cosatu's May Day march on 1 May 2015.
JOHANNESBURG - Sunday is May Day, the day traditionally focusing on workers and their interests.
Cosatu says it will host a number of rallies around the country.
This follows a decision by the union federation to centralise celebrations to reach workers in all corners of the country.
The union&39;s national event will be held in Mamelodi in Pretoria and will be addressed by President Jacob Zuma.
The theme is celebrating 30 years of defending workers&39; rights and jobs.
The National Union of Metalworkers of South Africa will be holding a rally in Mehlareng Stadium in Tembisa.
The union says they will use the rally to launch a Jobs Campaign that will unite workers across all sectors of the economy.
