The 16 actors fired from the Generations soap opera have approached the Commission for Conciliation, Mediation and Arbitration (CCMA) to seek reinstatement, they said.
The actors, organised under the "Generations Actors Guild" (Gag), said in a statement they were "unshaken" in their resolve to secure their demands.
These include a reduction to 10 working hours a day, provision of social benefits, an end to inconsistencies in remuneration, payment of royalties, and better working conditions.
The actors were fired on August 18 for going on strike over a wage dispute.
Gag said: "Throughout this process, we have engaged with our former employer and been clear about the fact that we are open to negotiation and discussions - but we are resolute in our commitment to transforming unfair industry practices."
The actors expressed gratitude to their fans, the Congress of SA Trade Unions and the Creative Workers' Union of SA for their support.
The labour organisations on Monday called for South Africans to boycott the show for a week in support of the actors' demands.
