The union for Air Vanuatu workers says management failed to attend a meeting with the union yesterday called after a strike on Monday.
The secretary general for the National Workers Union, Ephraim Kalsakau, says Air Vanuatu workers temporarily ended the strike after agreeing to further negotiations.
Workers chose to strike over a breakdown in discussions over a collective bargaining agreement, grievances over job security and severance pay.
He says the workers are now considering legal action.
"We've asked the commissioner of labour to look into a breach by the employer, as they proposed the meeting and we agreed to it in good faith. And them not turning up, as far as we're concerned it wasn't in the agreement so we'll wait for the Department of Labour to respond to us, and at the same time seek legal advice."
Meanwhile the Labour Minister George Wells also wants to take court action, declaring Monday's strike action illegal.
