Johannesburg - Congress of South African Trade Unions (Cosatu) general secretary, Zwelinzima Vavi says he will not be out for revenge when he returns to work on Monday, SAFM reported on Sunday.

On Friday the High Court in Johannesburg ruled that Vavi's suspension was invalid and unlawful. The labour federation suspended him in August last year after he admitted to having an affair with a junior colleague.

The National Union of Metalworkers of SA then lodged an application in the High Court in Johannesburg challenging the decision.

SABC news website reported Vavi as saying: “I am not going to that office to make people pay for having betrayed me, I am going to there to do my part and make a contribution in a collective of other leaders to ensure we overcome the crisis that is facing the working people, I will be at Cosatu offices after 9am and people can choose to be hostile to try and drink poison and hope that I will die as Nelson Mandela put it, but I will be there and prepared to work with everybody.”

Vavi said there were attempts to prevent him from resuming work on Monday, SAFM reported.

Cosatu leadership said it would meet on Tuesday to decide its next move after studying the court ruling. Vavi believes they want to use the meeting to renew his suspension, the report said.
