I think what the CEPs are arguing is that different people on the same base (In this case HKG) have different packages. For the case of overseas basings, everyone is employed by a shelf company and on the same conditions. If say half of people on the Vancouver base got housing and the other half did not then yes that is discrimination.
It would be great if everyone got housing everywhere. At Cathay we are all separated into different groups with different interests. Unfortunately the way things improve is for those groups to fight for improvements. Unfortunately one group will rarely help to support, or even care much about the gripes of the other group. Now it is the locals turn to argue their demands and instead of support or even being indifferent to it, you all jump up and down about something that does not even concern you? We are our worst enemy we really are. It is no surprise our conditions never improve and the way we beat each other up perhaps that is what we deserve.
