Some of the approximately 1,200 union workers begin a two-day walk-out against Ineos the owner-operators of the refinery in Grangemouth, Scotland, 27 April, 2008.

The workers are protesting Ineos' plans to end a pension scheme for new workers. The refinery closure has forced BP to close down its "Forties" pipeline system, which provides one-third of Britain's North Sea oil production.
