Using concession of travel for someone who works away from their family and returns to them every weekend

Q 1: I am from Jeddah. My family and I live in Jeddah. I was appointed as a teacher in a school in Al-Khurmah, 370 Kilometers away from Jeddah. I stay in Al-Khurmah from Saturday to Wednesday noon and then I go back to Jeddah. This takes place during the whole academic year.Is it permissible for me to shorten Salah during my stay in Al-Khurmah or not? If this is permissible, should I offer the Sunnah Ratibah (supererogatory Prayer performed on a regular basis) or not?

A: You must offer Salah in full during your stay in your working place, because you intend to stay more than four days whether you are staying alone or with your family. Therefore, the rulings of a traveler are not applied to you or your teaching colleagues. It is Mustahab (desirable) for you to offer the Sunnah Ratibah.
