While New York's Museum of Modern Art has settled its union dispute, the ongoing staffing crisis at London's National Gallery of Art seems poised to continue, with a strike involving all union workers set to begin on August 17.

The Public and Commercial Services union has informed the museum of its plans, which include four additional days of strikes on August 4, 5, 6, and 12. The union voted overwhelmingly in favor of an all-out strike.
