Look at the printed media of the era. I won't claim that you couldn't open a paper without finding an article demonising the unions, but it certainly
felt that way - an ever-present onslaught aimed at convincing people that the unions were selfish, that they achieved nothing for the electorate as a whole, just for their own sectarian selves (obviously missing the entire point of being in a membership organisation.
) - because that was what those with power wanted represented. That it coincided with a leader of the Conservative party who held the working classes in complete contempt and would have sold her own orifices on a nightly basis if it had helped destroy the trades unions that were such a threat to her party was just the icing on the cake for power.
