A coalition of aviation workers’ unions has grounded operations of Caverton Helicopters in Lagos and Port Harcourt over alleged indebtedness to former workers and anti-labour activities.

The picketting exercise, led by the National Union of Air Transport Employees (NUATE) and Air Transport Services Senior Staff Association of Nigeria (ATSSSAN) and other three unions, was a fall-out of last week’s peaceful protest disrupted by the police.

In a circular issued yesterday to workers, the unions said the picketing fully begins today and runs indefinitely pending when the management offsets the alleged arrears.
