The authorities have imposed a ridiculous "minimum service level" of 90% for this strike, which means that in practice there is no strike. So unless they start with some other type of industrial action (which nobody is talking about right now as far as I know), you will not even notice it.
And during none of my recent departure I have noticed any unusally large lines at security (for what this is worth, since I am not using he normal security line myself - just seeing it from afar).
