Employees of telecom equipment maker Alcatel-Lucent attend a demonstration in Orvault near Nantes, western France, October 10, 2013. France warned on Wednesday it could use new rules to block a plan by telecoms company Alcatel-Lucent to lay off 900 French workers, but unions and government sources questioned whether the state would go that far. The banner reads "no layoffs". REUTERS/Stephane Mahe (FRANCE - Tags: BUSINESS TELECOMS EMPLOYMENT)
