Two aviation unions on Monday shut down the operations of Arik Air over non-payment of salaries.
They are the National Union of Air Transport Employees and the Air Transport Senior Staff Services Association of Nigeria.
The unions claim that the salaries of the staff have not been paid since April after placing 90 percent of the workforce on compulsory leave and other anti-labour practices.
Among the demands of the unions are payment of outstanding salaries arrears, signing of conditions of service, remittance of pension, tax, and statutory deductions to the appropriate authorities.
The unions say the strike will continue indefinitely until their demands are met by the management of the airline.
