The workers were dismissed in 2013 after a strike where coaches were torched and damaged at an estimated R42 million.
However, in 2016 the Constitutional Court declared the dismissals unfair, but workers were still not reinstated.
On Thursday, Prasa employees gathered in Parktown, Johannesburg with Saftu and the National transport Movement, for a march to the company's head office to demand clarity on when they can resume work.
Saftu had written to Prasa about the reinstatement issue but had received no reply.
Saftu general secretary Zwelinzima Vavi tells Ray White on The Midday Report that, in fact, now Prasa has agreed to the reinstatement of the workers.
They were dilly-dallying and that is why we decided to march. But before we could even march today, they (Prasa) wrote back a letter to say, no hold on, we are deciding to reemploy them, to reinstate them.— Zwelinzima Vavi, General Secretary of the South African Federation of Trade Unions
Vavi says the first group, who requires no new training, will return to work on Monday. Others who need refresher training will receive it and then return to work.
And so the whole issue of the march became a celebration at the park today. We are not marching, we are celebrating.— Zwelinzima Vavi, General Secretary of the South African Federation of Trade Unions
The fight is now over, says Vavi.
