When I was a union rep for the GPMU (mid/late 90s), we used to make bets on how long it would take the conversation to turn to Wapping when two full-time officials were in the same room at the same time.
There was still a lot of bitterness from some of the low paid clerical/admin folk in our branch who'd gone out in support of the printers, got sacked and ended up on the dole while the (much better paid) printers were ultimately a lot less replaceable once it was all over. Not sure how true some of the stories were but the resentment was very real.
