A strike like this will only open the doors to private mail service providers. They will be 'larfing ones cocks orf'.
I used to be a miner, and it did'nt work for us.
Funny story though: A few weeks ago, me a few mates were in Tenerife and after a few beers one night, headed towards JAZZIMO, a sort of Soul/Motown cabaret bar. Anyway as we walked up to the door, this bloke come up to us and said he and a few of the staff were on strike and requested we did not cross the picket line.
As you can imagine, we did not go in and being in the mood, helped the cause by becoming 'flying pickets' and helping the strikers pursuade other revellers to stay away. Great fun, but seriously crossing a picket line is not an option.
Good luck to the Posties, but with so much cheap labour about, beware and dont be surprised if you get replaced sooner rather than later.
