The new crews are being paid, just not full pay. Their contract states that they will be on training pay until they complete training (completion of a line check). I believe the intial new hire class dragged on and someone promised them full pay when the arrived in Al Ain. But, no one bother to clear it with the president of the company. So, per the contract they are being paid correctly.
I guess the guy who made the promise should make sure that the President of the company approves of deviation from the contract. Especially when it comes to pay issues.
There are also a couple of guys with medical issues who I believe aren't being paid. Something to do with getting a medical in the UAE. Per the Midex contract if you can't get a medical and license in the UAE you can't be employed there.
So, looks like a few people are just trying to make Midex look bad.
