A 17-member team addressing the media in Johannesburg on Monday described the dominant COSATU faction as a dictatorship undermining interests of the working class.
The coalition among others include SACCAWU, CWU, FAWU, DENOSA, PAWUSA, SAFPU and SASAWU.
The unions accused Blade Nzimande-led SACP, the ruling African National Congress and a faction allegedly led by Sdumo Dlamini within the federation for fuelling divisions in COSATU.

“This has been a sad and shameful week for South Africa trade union movement and the working class in general,” read the statement issued by the unions.
“COSATU, once a militant and profoundly democratic trade union federation, which was an envy of the workers worldwide, has been reduced to a factional shell of its former self and glory.”
The coalition of the unions fighting for Numsa to be reinstated added that the hard decision made by COSATU’s central executive commission was unfortunate.
“The expulsion of Numsa, which represents 350,000 metal workers, by 33 CEC delegates, many who had no mandate to do so, is an attack on the organised working class,” added the coalition statement.
Unions said allegations levelled against Numsa were without substance and not credible enough to warrant the decision to fire the powerful union.
“All of the accusations levelled at Numsa are simply not credible, and it is the duty of all trade unionist to defend them against the trumped up chances, and unsubstantiated accusations that have been levelled against them,” read the statement.
“The expulsion of Numsa will not solve the intractable paralysis that has consumed COSATU since its watershed 11th Congress of 2012 and its revolutionary-compelling resolutions.”
The coalition said the SACP was cash strapped and like ANC had used the federation and Numsa when it best suited them.
The nine unions are also fighting for COSATU general secretary Zwelinzima Vavi’s survival whose power base has been waning following a sex scandal with a female employee at the federation premises.
