In a joint letter dated July 31, the unions expressed frustration that, despite concluding negotiations with NAMA management over eight months ago, agreed salary adjustments remain unimplemented.
The letter was signed by the General Secretaries of four unions: the Air Transport Services Senior Staff Association of Nigeria, National Union of Air Transport Employees, Association of Nigeria Aviation Professionals, and the Amalgamated Union of Public Corporations, Civil Service, Technical and Recreational Services Employees.
The ultimatum, which expires on August 7, warns of a total withdrawal of services by aviation workers if the issue is not resolved.
The unions lamented that the salary adjustment negotiation had been concluded with the agency's management, but regretted that its outcome had not been implemented in the past eight months.
They stated that their members had expressed frustrations against the non-implementation of the salary adjustments agreement over the months.
The letter reads, "Recognising that notice of ultimatum has already been issued and served by our branches, which our national unions have adopted. A seven-day notice of withdrawal of services from today, Thursday, the 31st day of July, 2025, is hereby issued."
The unions threatened that by the expiration of the ultimatum, should the situation persist, all workers in NAMA will commence a withdrawal of their services nationwide.
They advised every NAMA client to be aware of the notice.
