"I think that hopefully the public just wants to see their favorite shows back on the air. In terms of '30 Rock', everybody’s just happy to be back working. We are deciding that the strike did not happen in our world [because] for people viewing at home. the real strike was a big enough pain, and they probably don't want to hear anymore about it...
"Before there was a strike we did have a strike story and we may save that for later down the road."
Of course, Tina Fey's "our world" is Toobworld for us. And as such, without actually being confirmed, it's connected to every other TV show, past and present and from countries.
So as long as nobody else does a story about the WGA strike against the AMPTP, that attitude is fine. After all, Toobworld is not the real world and not every historical event isn't going to be portrayed as it really happened. (For instance, the ethnic cleansing in the Balkans in the late 1990s was part of the Eugenics Wars in Toobworld.)
I'm not sure any other TV show will bring up the strike once they return to the air; first off, mostly because they don't really deal with the business of TV, (Although it might be mentioned because life does center around TV viewing for many TV characters as reflected in their pop culture references.)
But if somebody does bring it up, it doesn't negate Fey's decision not to address it. Just because '30 Rock' doesn't bring it up, that won't mean it didn't happen in Toobworld. It's just that the 100 day (plus?) strike must have happened between episodes of the show.
