Good or Bad ?
My view is that very rarely in recent industrial action have the majority or even a large minority of union members voted for strike action ,they where simply a majority of those who voted .An example cited in the article i have linked to is that the planned London bus strike on Jan 13th was voted for by only 16% of members but because of the way unions work that is considered a mandate to strike ,so yes i largely agree with the planned changes
