Johannesburg - Cosatu's drive-slow campaigns against e-tolling will continue as they irritate politicians, the trade union federation in Gauteng said on Wednesday.
"This is not the end of the drive-slows in the province," the Congress of SA Trade Unions' Gauteng secretary Dumisani Dakile said in Johannesburg.
"It also irritates a number of politicians and we are quite very happy with that irritation we are causing."
Dakile said the drive-slows were effective in raising awareness.
Cosatu has a march planned for Thursday, to hand over memorandums to Gauteng's premier, transport department, legislature, the Chamber of Mines of SA, and the Hawks.
The cost of the construction of the roads and the 2010 World Cup stadiums was inflated, Dakile said.
"We know the prices were inflated. The Hawks and police must do a criminal investigation," he said.
