EK is not the subject of UAE Labour Law.
I went to the Ministry of Labour when I had problem with EK and they told me to go to the General Directorate of Residency in Dubai, because Ministry is not responsible for EK. In the Directorate they asked me about my business with them, I told them that I want to complain on EK and they told me "good luck with that it's a waste of time" in a sarcastic way.
This is EK's official recognition that EK is not the subject of Federal Law:
In another words, nobody is protecting foreigners in UAE.
