Is there any chance that this sciopero nazionale could get rescheduled to the 20th?

We arrive at VCE on 10/20 and I'm just wondering if there's much to be concerned about?

I don't really see the strike impacting us one way or the other, apart from lunch reservations on the isle of Giudecca on 10/21. I'm sure our hotel can arrange transportation though. The Gritti has their own boat. We have no other fixed plans that day.

I'm slightly worried about the possibility of it being pushed ahead one day, as it would turn into an enormous inconvenience and problem if it occurred on our day of arrival. I suppose we should count ourselves lucky that it got scheduled for the 21st.
