UK rail workers to strike again July 27 over pay dispute

British rail workers will go on strike on July 27 over an ongoing pay dispute, a month after the country's most disruptive railway strike in three decades paralyzed train networks across the U.K.

The National Union of Rail, Maritime and Transport Workers said Wednesday its members will walk out for 24 hours, threatening travel chaos during the busy summer holidays.

Union leaders said they have rejected a new pay rise offer from Network Rail to resolve the dispute over jobs, pay and working conditions.

The union staged three strikes last month that saw 40,000 workers walk off their jobs, crippling services across the country. Unions say a 4% pay raise this year is not enough with inflation at 9.1%.
