I'm waiting for holiday tickets too - we leave next week. Maybe it's my fault for leaving it so late, but the postal system in this country is an absolute disgrace. People will probably disagree with me here, but at the end of the day the postal workers can either accept that Royal Mail is going to modernise and jobs are going to be lost (like in any industry that has huge potential for modernisation and competition), or they can continue striking, losing their pay and almost certainly resulting in a much bumpier ride.
