Sadly there isn't an answer to your question. The current legal issue of the retirement age has now been passed by the Senate and the National Assembly. So in theory's that's been done and dusted. But that may not stop folk striking, especially if the more militant members of certain trades unions have anything do to with it.
And of course other grievances could arise in the meantime ....
Just plan sensibly avoiding tight connections if flying and take enough money to cope with a delay at an airport and as you always should do before leaving home, make sure you have taken out adequate travel insurance.
Speculation is always a sure-fire recipe for dissent and disappointment!
