PARIS (Reuters) - Worker unions representing Air France staff called for a strike on March 23 after failing to reach a deal on pay with management, according to a document seen by Reuters.

The strike would come a month after similar action in February, which resulted in the cancellation of more than half of the airline's long-haul flights.

Worker unions representing Air France pilots, cabin crew and ground staff called the strike amid demands for a 6 percent pay rise, which the airline has refused to meet.
