Aviation workers’ unions, yesterday, warned of impending indefinite strike action if the authorities fail to resolve the nagging non-implementation of Condition of Service, and other welfare-related issues in the next seven days. The General Secretary of The Amalgamated Union of Public Corporation, Civil Service Technical and Recreational Services Employees, Sikiru Waheed, told reporters in Abuja that the strike was to warn the travelling public to make other plans as they intend to shut down the airports should their demands go unmet. Recall that the coalition of aviation workers’ unions made up of members of the National Union of Air Transport Employees, Air Transport Services Senior Staff Association of Nigeria, the National Association of Aircraft Pilots and Engineers, the Association of Nigeria Aviation Professionals, and Amalgamated Union of Public Corporation Civil Service Technical and Recreation Services Employees, recently bemoaned the non-implementation of the CoS about seven years after it was negotiated with the workers.
