I remember about 20 years ago or so, maybe less but Ken was Mayor, there was a dispute brought that was entirely resolevable and management said just call it off and we sort it. The RMT dug in and tacked on more issues/cases.
In the end it transpired that while the strike was unnecessary, it was done for two reasons:
- because striking is in the culture of the RMT and its 'identity' as a strong union
- to flush out moderates who didn't support the hanrdline stance of the leadership (i.e. Bob Crow)
