International Schools: Unjust by definition?

As I was typing a letter to a potential employer, I kept recalling something I'd heard recently:

People in the employ of the Great American International School who are hired at a job fair have a very advantageous contract. The school pays for their trip to a job fair to find a new job.

I think of this because one colleague started this term late, as he'd spent a week away, looking for a new job--all paid for by my current employer.

But I believe that I am in no way inferior to this person.... yet as I was sitting in the teacher's room, typing a letter to a potential employer, I had to endure interruption by another colleague with the most advantageous form of contract...

And then there are my colleagues who are citizens of our host country--even more badly paid, with even fewer privileges.

Something is wrong with this picture.
