The All Truck Drivers Forum and Allied SA (ATDF-ASA) possibly plan to hold national protests from Monday.
Fidelity Services Group says although unconfirmed, the risk exists that the protest action may start over the weekend and comes on the heels of a protracted six-year history of violence within the South African trucking and road freight industry.
It says tensions have been apparent within the industry since 2018, with the main point of concern related to the employment of foreign truck drivers.
The ATDF-ASA contends that several trucking companies in the country routinely and illegally hire foreign truck drivers at a lower cost to increase profits, leaving South African truck drivers jobless.
According to Fidelity, major routes in the country might be affected, including the N2 and R75 in Gqeberha, the N10 at Nxuba (formerly Cradock), and the N9 at Middelburg in the Eastern Cape.
Fidelity says the Information & Tactical Operations Centre (ITOC) is a centralised hub that receives real-time and early-warning information from various sources and will monitor the situation and provide regular reports.
