Then you should be fine as strike affects Iberia operated flights.
Regarding the questions about flights leaving on thursday and arriving on friday, i believe that there should be no problem as they are operated in roundtrips starting in Spain on the same day (for example flight JFK-MAD On thursday has flown beforehand MAD/BCN-JFK! so you should be safe. The problem comes with the connection in MAD on friday.
