Workers in KwaZulu-Natal have been called on to join the strike in the contract cleaning sector, the SA Transport and Allied Workers' Union (Satawu) said on Thursday.
“They are currently not on strike because they have a separate bargaining forum,” chief negotiator Lungile Ntshuntshe said.
The strike is currently affecting cleaning at old age homes, private hospitals, shopping centres and government institutions in every province except KwaZulu-Natal.
Six more unions would join the strike on Monday.
A full-blown strike would lead to over 100,000 contract cleaning workers walking off the job.
