Aviation unions have embarked on a two-day nationwide warning strike to protest the unpalatable working conditions and entitlements of their workers.

After issuing a warning in a memo signed on Friday, the unions said an indefinite strike would commence if the government failed to address the approval and implementation of the Condition of Service (CoS), the new salary structure for the workers, and the planned demolition of the offices of the aviation agencies.

Leadership reports that as at 6am on Monday, the protests began as vehicular movements were totally grounded as the aviation unions blocked all entrances leading to Nnamdi Azikiwe Airport in Abuja and Murtala Muhammed Airport in Lagos.

The unions involved are the National Union of Air Transport Employees (NUATE), the Air Transport Services Senior Staff Association of Nigeria (ATSSSAN), and the Association of Nigeria Aviation Professionals (ANAP).

Others are the National Association of Aircraft Pilots and Engineers (NAAPE), and the Amalgamated Union of Public Corporation Civil Service Technical and Recreation Services Employees.

Also, many passengers who arrived at the airport to catch their flights to various destinations were seen trekking following the blockade and the head office of the Federal Airports Authority of Nigeria (FAAN) was locked.
