They said their final salary pensions were changed
BP tanker drivers of the Transport and General Workers' Union postponed their planned 5-day strike in a dispute over pensions, to allow union leaders and management to make an arrangement.
The dispute arose when the drivers were moved to BP from logistics firm Exel earlier in October.
They said their final salary pensions were changed to an "inferior" scheme.
The drivers said the move to money purchase schemes had reduced the value of their pensions.
