I have read that there are some train strikes (Italy) in December. Is this likely to happen in January?
Need more details to even attempt to provide an answer.....
What cities, more specific dates (if you know them) would be helpful.
Note that many threatened strikes get called off at the last minute due to settlement,
court action, etc, so even if it looks like there may be a strike, it does not always happen.
Also, in Italy, there are certain times of days (more or less rush hours) where train
strikes are banned by law.
From mid to late January -- travelling around Italy (Rome, Verona, Lucca, Venezia, Napoli...)
Are January strikes likely?
I'm no expert, but the Winter Olympics are in Italy in 2026, and strikes would not look well to the international community.
As already mentioned, announced strikes often don't happen and certain rush hour trains run regardless. If you want to monitor the announced (potential) strikes, you might bookmark or keep open this official governent website (with English translation) https://scioperi.mit.gov.it/mit2/public/scioperi. As it gets closer to your travel dates, if there are strikes listed that appear to affect you, often someone on this forum can help interpret the details and suggest alternatives if you need help figuring it out.
Here is the official strike calendar for Italy: https://scioperi.mit.gov.it/mit2/public/scioperi
Keeping mind that strikes are often called off (they are often a negotiating tactic) and many are regional and confined to one union, industry or another. The only significant National strike I see is an airline strike for 24 hours on 1/9.
The only possible train strike I see that might cause you problems in the north is: Ferroviario PERSONALE SOC. TRENORD strike from 1/12 - 1/13. Trenord handles regional trains in the north of Italy (for tourists especially around lakes like Lake Como) so if a regional strike happens it could lock that up.
Fast trains between big cities have trains that are guaranteed to run - usually early and late - and there are both public and private fast train companies so unless it is a big nationwide strike - which I have experienced - you can always look to other one for possible relief.
So at the moment it seems pretty quiet and you'll probably be fine. Italy's barely contained chaos is part of its charm and train travel is always an adventure.
Have a great trip,
