Yes, if they hammer the unions too hard, then the unions become not just ineffective but pointless, and i think they'll soon find out the role that the TUC unions have had in disciplining the workforce - persuading people to not take things into their own hands, to wait for union negotiations, etc. Its not that i'm predicting loads of wildcat strikes or organised action - except in the industries in which such action already happens on a semi-regular basis, and outside the very limited influence of more radical groups - but i think there'll be a big upturn in "mistakes" at work, people going off sick because of stress, individuals kicking off or walking out of workplaces, stuff like that.
