A point of order....
Just as a point of order 'the Union backed Labour Government' in it's 13 years of office did not introduce any radical changes to the law relating to strike action. The vast majority of the current law concerning strike action dates back to the 1980s and was (IMHO) rightly introduced in the wake of the Miners Strike of 1984-85 by a firmly right wing Government.
And to be honest, does any political party give a toss about such a small trivial strike?
