Oh I don't know. I freak out if my internet goes down, and imagine the effect on business if there are outages, and a lot of government services will also not work without internet connections, and where businesses will try make another plan, government dept's will just say sorry, can't get onto the system, come back in a few weeks.
I suppose the difference will be if they sommer just strike, then it's not such a huge impact, but if they actually kill internet connectivity on a big scale, it'll screw the whole country.
