Gautrain spokesperson Kasagee Nayger said that normal train services would resume on Friday.
The union has served the Bombela Operations Company (BOC), which manages the Gautrain, with a 48-hour strike notice. This comes after failed wage negotiations between the union and management.
Many claimed that they had not received a cent from the Temporary Employer/Employee Relief Scheme (TERS).
Trade union Numsa said the protest outside the UIF offices in Cape Town related to non-payment from the Temporary Employee Relief Scheme.
The union said that the protest comes after many queries raised with the Employment and Labour Department regarding the non-payment of Temporary Employee/Employer Relief Scheme administered by the UIF.
The administrators took control of state-owned SAA in December after almost a decade of financial losses and published a rescue plan in June following repeated delays and wrangling over its future.
Numsa said it’s left with no choice but to mobilise its members at the steel manufacture after employers varying down workers’ wages and benefits.
About 2,700 workers will be retrenched and paid severance packages while 1,000 workers will be retained.
Business rescue practitioners at the troubled airline wanted the court to set aside a court decision to halt retrenchments at SAA until a business rescue plan is adopted.
This comes after a meeting on Friday where the department indicated its decision to withdraw from the leadership consultative forum established to find the best way to restructure SAA.
The unions say they are exploring their legal option to stop the liquidation of troubled the national airline and SA Express, following the Finance Minister's statement that there will be no more bailouts for SAA.
Judgment has been reserved in the appeal case between the South African Airways (SAA) business rescue practitioners (BRP) and three workers' unions.
The business rescue practitioners’, who took over SAA in December, published their restructuring plan last week and expected the vote to take place on 14 July.
The BRPs and SAA then argued that there was a reasonable prospect that the facts would receive a different treatment by the Labour appeal court and leave to appeal has now been granted.
Last week, the Labour Court ruled that the business rescue practioners must first produce a business plan before they can take steps to retrench workers.
Numsa and the SA Cabin Crew Association took the practitioners to court, claiming that their retrenchment plans were unlawful.
Business rescue practitioners gave all workers at SAA until next week to accept severance packages.
The SAA business rescue practitioners have asked unions representing workers at the airline to send alternative ideas or queries about their proposal to retrench workers by today.
