It's often hard to make out what is going on in an industrial dispute. By the time you get to a strike there have already been hundreds of hours of negotiation. The traditional media adopts a bored indifference and it's quite tricky to drill down to what the participants see as the issues first hand.
At the station for an early train today and i managed to snap these leaflets from the picket line to give one side of the story and found a link to a TfL statement giving their side of the story. Also TfL's strike information page for travellers is here.
I am not looking to kick off a debate in the comments on the merits of strikes etc – just trying to make some direct information available.

I saw Bob Crow this morning at a picket line in front of King’s Cross station. He got berated by passers-by. He had to walk off and complete his media statements and interviews at Euston.
