Members of the Police and Prisons union, Popcru, will take to the streets this week.
About 42 000 police administrative staff will march in all the provinces on Wednesday to demand that the SA Police Service honours an agreement to change their salary grades.
Popcru's Thetho Mahlakwana says the agreement was signed and states that public service employees should be integrated under the SAPS Act.
She says this will also ensure that they are eligible for a raft of benefits which are currently being enjoyed by their colleagues in uniform.
"The members who will be marching will be members of TSA, and the staff of the 10 111 operators and various other support services,"Mahlakwana said.
The Eastern Cape leg of the Popcru march will take place in King Williams Town to police headquarters in Zwelitsha.
