The National Union of Mineworkers of South Africa (Numsa) on Thursday accused the business rescue practitioners (BRPs) for private-sector airline group Comair of trying to blackmail employees into giving up their rights, ahead of a crucial meeting of the company’s creditors on Friday. The union also expressed concern about the investors and management proposed for the relaunch of the airline. Numsa condemned the BRPs “in the strongest terms”. It asserted that the BRPs had not consulted Comair’s employees on the proposed business rescue plan and that they were trying to unilaterally force workers to accept changes to their terms and conditions of employment.
