PETROL station workers have revealed in a startling survey the level of abuse they are facing as a result of the crisis over supplies.

Staff say they have been left feeling stressed and anxious by the abuse from annoyed motorists as long queues take their toll.

The Usdaw union said a survey of its members showed a “significant minority” of motorists are taking out their frustrations on staff, swearing at them and even deliberately driving cars towards workers.
