IMHO, the nature of the FBU industrial action has much to do with the leaders of the affiliated unions coordinating industrial action most likely to get media attention rather than action that is most likely to achieve results.
I say this because I am in a dispute where this is clearly (to me) taking place. A strike ballot with a feeble turnout (~32%) showed a clear preference for action short of a strike and weaker support for a strike. However, national leadership started with strikes which will have limited effect compared to cleaver ASOS. A re-run of the failed pensions dispute and doomed to have the same non-success unless headlines are the objective.
