Special Delivery is not always guaranteed next day during the strike, but supposedly it is prioritised. Managers and other staff not striking go out delivering Special Delivery on strike days.

Oh how I hate having to collect mail. Its sad, here I am in Sheffield one of the biggest cities and our delivery office is only open in the morning and you have to allow 48 hours after attempted delivery before you can arrange redelivery or collect it. Yet they wonder why Royal Mail are losing business.
