I think the point isTHY is not a an Airline for expatriate. The "ideology" behind make it just a short time stepping stone to somewhere else. On the other end they send email asking pilot to tell their friends to join. I really don't think so.
And that's the point. Either they recognize that they need a certain amount of expats or their strategy will fail. If a company need expats they have to treat them somehow different. That's the way how the expatbusiness is working.
