Tanker drivers at an oil refinery will take industrial action from Friday in a dispute over pensions and pay.
Unite members at Grangemouth will walk out for three days from Friday morning. The workers, employed by BP, will ban overtime from Monday.
Unite said the industrial action will hit aviation supplies and deliveries to BP forecourts across Scotland and the northeast of England.
The union said 90 per cent of the 42 drivers balloted voted for strike action to defend pension rights and in protest at the loss of a company share scheme as a result of the aviation contract transferring to another firm.
