Hello Gillegan,
I was told the Zimbabweans recently challenged the ERP Policy using the official procedures and won after a lengthy struggle. As a lot of them had been kicked out of their home country and had been forced to move elsewhere they probably had a good argument.
Speak to some of them, but the "official channels" appear to work. A comparitively small number making a strong case, and EK tried every excuse to put them off and wear them down - but eventually saw reason.
Guess you need a few people, fighting a strong case and a lot of perseverance.
