The Congress of South African Trade Unions, (Cosatu) is believed to be seeking an interdict against Vodacom's proposed May 18 JSE listing.

According to Reuters, the trade union is also trying to overturn a recent decision that lets Telkom transfer its stake in Vodacom to Vodafone without getting written permission.
Cosatu is believed to be concerned about possible job losses should the deal go through.
Telkom is due to distrbute 35% of its Vodacom stake to shareholders and transfer 65% to Vodafone ahead of Vodacom's 18 May listing.
