Everything from air travel to subways to garbage collection is being threatened.
That's too bad. I remember how disappointed the wife and I were when we visited France a year and a half ago. We had reservations for the high-speed rail (TGV), although I don't remember the destination. Day before we were to depart, the transportation workers decided to randomly strike. We were a small travel group- can't imagine the chaos to ensue if something(s) similar occur with all the masses from all over the world involved...😳
