Scores of Pikitup truck drivers were protesting outside the company’s head office in Braamfontein near Johannesburg CBD on Monday.
It was unclear what their grievances were - but they blocked off the Nelson Mandela Bridge and Jan Smuts Avenue with trucks.
A man who works at a nearby office and described what he saw.
“I’m on Nelson Mandela Bridge. There’s a massive strike here by Pikitup. The Pikitup head office building is completely cordoned off with trucks all over. The Pikitup trucks have filled up the roads,” he said.
