Violent acts by workers at the headquarters of troubled flag carrier Air France a day ago are a national embarrassment that reinforces the very image the country wants to shake off, French political leaders said today. 

"This image hurts our country," said Prime Minister Manuel Valls.

Pictures of senior Air France officials with their shirts ripped and torn off adorned world media today. 

President Francois Hollande has sought to put across a more business friendly image, and to show that France has the stomach to implement the sort of free-market reforms that can erode working conditions and pay as well as boost growth and employment. 

Since then, however, French farmers, taxi and truck drivers, ferry workers and others unhappy with the impact on their business of globalisation, the digital revolution and eco-friendly taxes have been involved in violent protests - in some cases securing concessions and policy U-turns. 

The workers involved in yesterday's actions were protesting against the airline's attempt to stay competitive by getting more work out of its pilots and cabin crew for the same pay. 

Like other European carriers, Air France, part of the Franco-Dutch group Air France KLM, faces harsh competition on short-haul routes from a new generation of lowcost airlines and on long-haul routes from Gulf-based airlines backed by their countries' sovereign wealth. 

Air France officials say failure to secure the air crews' agreement for the plan has now forced them to come up with a more draconian one, which cuts 2,900 jobs and pulls the airline out of 10% of its long-haul routes. 

"It would be a drama for our country if a business so symbolic were to find itself in trouble because a minority refuses to adapt to a changing world," Valls said at a specially arranged visit to the airline's headquarters near Roissy airport north of Paris. 

Hollande, who is receiving a group of venture capitalists this week to encourage investment in the euro zone's second-largest economy, showed that he was also embarrassed by the scenes. 

"This has consequences for the attractiveness of the country," he said on Twitter. 

Meanwhile, Transport Minister Alain Vidalies said talks aimed at resolving the dispute should be resumed as soon as possible. 

"I think the best French response would be to respond to those abroad who see a caricature, that these events are not France, and that we can get back on track by talking," he said on French radio. 

Air France has launched a legal complaint over yesterday's incident, which has been condemned by management, unions, and government officials alike. 

Vidalies said there should be penalties for those involved. Asked whether the government should intervene more directly in the dispute given its 17% stake in the business, Vidalies said nationalisation was not on the cards.
