You would be hard pressed to find any EK pilot that is happy anymore. As been mentioned many times in many different ways the direction the company has decided to take in the last few years is very troubling as there is absolutely no reason for this southward trend.
If they decide to add DECs to the mix that would be the last straw for a lot of FOs. How much more garbage can they take? Plus what kind of pilot would join Emirates knowing all that the company does and that DECs are coming in front of the new FOs.
