Johannesburg - The National Union of Public Service and Allied Workers (Nupsaw) will give Home Affairs Minister Malusi Gigaba 7 days to respond to its demands.
Just more than 50 union members put up with the wet weather and marched to the department in Pretoria on Friday.
The union said it would continue to fight until its demands were met on overtime. It is not clear what action the union will take if its deadline is missed.
"Don't be fooled by our small numbers here today. Its not just a small probe. You going to be surprised. This is the beginning of things to come if you are not going to listen in the next seven days," said Nupsaw general secretary Success Mataitsane.
The main reason for the march was for members to voice their concerns about the staff members working on Saturdays not receiving overtime pay. Home Affairs started operating on a Saturday in 2005.
The union is also demanding that the department ceases o suspend its members for not attending work on Saturdays.
"The employer must stop immediately suspending our members for not coming to work on Saturdays. They must be paid for overtime," said Nupsaw national organiser Solly Malema.
The department and the unions have engaged extensively on the issues raised by the department and the matter was referred to the General Public Service Sectoral Bargaining Council (GPSSBC), the Labour Court, and the Labour Appeal Court. It is now pending before the Constitutional Court.
The department sent out a representative to collect a memorandum of demands and assured the union it would pass it on to the necessary officials.
