Hundreds of thousands of French workers are expected to join the country's second nationwide strike in two months. Unions are protesting against President Nicolas Sarkozy's economic policies. Unemployment has reached two million and is expected to rise further. Demonstrations are planned in about 200 towns and cities. Schools are to close and public transport faces disruption. Organisers hope the protest may be bigger than one in January, when about a million people joined protests. The unions are urging the government to do more to protect jobs and wages.
