Spokesman Jacob Modeming, said they delivered a memorandum of demands to co-operative governance MEC China Dodovu and the district mayor of Bojanelo, Lowie Diremelo.

They called for the immediate resignation of political heads and municipal managers of the Rustenburg, Moretele, Moses Kotane, and Madibeng municipalities, and claimed some municipalities needed to be put under administration.

"Municipal workers are concerned [about] the unacceptable levels of favouritism and nepotism... political interference in administrative matters, and rampant corruption taking place on a daily basis in municipalities in the province," said Modeming.

The union produced a lengthy document detailing acts they considered to be that of favouritism and nepotism committed by specific municipal heads.

They demanded answers for mismanaged funds and money which they claimed was unaccounted for.

Samwu called for explanations behind the appointments of people they said were linked to municipal managers in a personal capacity.

"We are giving them 10 working days to respond," said Modeming.

He claimed the local protest would be followed by national protests.
