Unite advert - P.S.
As I have touched on the cock-up theory and the conspiracy theory, perhaps I should mention at least one alternative. Could it be that they have completely given up on mounting a credible strike, and switched to the 'guerrilla tactics' that they hinted at a while back?
This would make more sense for them, but not very much, as it would probably have very little chance of success and is fraught with danger.
Anyone else got any other explanations for this latest bizarre turn of events?
