I've just checked the relevant section on the gov.it website and indeed there are quite a few strikes scheduled for that day (it seems that a number of handling agents may also call it a day, depending on their affiliation with the trade union[s] who announced the strike in the first instance). I can see that most strikes are planned from 10AM to 6PM hence I'm afraid this is likely to have a significant impact on operations. Please let me know should you need any specific advice on your travel arrangement.
