Willie Madisha's reign as president of Cosatu now depends on the central executive committee.
The committee already has a critical report by a commission tasked with looking into Madisha's conduct.
The report is so damning that Madisha, suspended five months ago, seems to give the executive little room to manoeuvre other than to ask him to relinquish his post.
The suspension was a sequel to Madisha's claim that he personally handed a R500000 donation from controversial businessman Charles Modise to SACP president Blade Nzimande.
The team investigating the R500 000 claim has already handed its report to Madisha and Nzimande.
Madisha was suspended after he was involved in a public spat with Nzimande over the donation, which Nzimande denies receiving.
According to a source, the report, between other things, attacks Madisha for bringing divisions within the ANC, SACP and Cosatu alliance.
"The donation saga was meant to undermine Nzimande and weaken the SACP voice before Polokwane," said a source.
The report also castigated Madisha for not supporting Cosatu's preferred candidate Jacob Zuma before the ANC Polokwane conference in December.
Madisha allegedly told union members in Limpopo not to vote for an immoral leader.
The committee will also analyse the ANC conference, discuss the power crisis, interests rates and food prices.
