Citing "no work, no pay and no benefits," Vodacom has blocked strikers from making calls on their fringe benefit packages.
Striking Vodacom employees were outraged that the company had blocked their cellphones, the Communication Workers Union (CWU) said on Friday.

This came after the service provider blocked the strikers' cellphones, citing a "no work, no pay, and no benefits" policy.

CWU spokesperson Mfanafuthi Sithebe said: "Vodacom confirms our long held view that the company has employed reactionary expatriates with no knowledge of the labour laws and the supreme law of the country."

He hoped Vodacom would not extend its "no benefits" policy and cut off medical aid as well.

Vodacom spokesperson Dot Field said on Thursday that strikers had been locked out.

Field said the cellphones were not blocked and the workers were free to insert their own SIM cards into the handsets.
