(VOVworld) - France's longest rail strike in years entered its seventh day on Tuesday after the first meeting between trade unions and officials didn’t reach any agreement.

The strike has already cost 80 million euros in lost revenue and refunds

The strike has crippled France's rail network as the country's crucial tourist season enters its peak. The rail operator SNCF - National Society of French Railways – said that up to two-thirds of trains were cancelled on some high-speed TGV lines, while only one in two trains were running on other lines. International lines to Spain, Italy and Switzerland were also disrupted, but Eurostar links to London and Thalys lines to Brussels and Amsterdam were operating normally. The strike has already cost 80 million euros in lost revenue and refunds.

The strike has been the biggest industrial action since Hollande's government took office two years ago. Hollande is struggling to bring France's deficit under control, improve the stagnant economy, and stem rising unemployment. However, Holland’s efforts have brought little success and his approval rating has decreased to only 18 percent, the lowest for a President in modern times.
