Where does it say the HK EO allows for out of seniority lay offs. ? It makes no such pronouncements. In fact it doesn’t even discuss seniority. Our C of S does. And again if they have reached the situation that they are impoverished enough to consider lay offs you can kiss goodbye to individuals returning from their bases to HK, so called global seniority or not. And our C of S are worthless then anyway.
And what recourse would these based individuals then have. ? If things are that dire they are hardly unlikely to be able to sue a non existent organization. Take a look at what can be done with an allegedly superior EBA (Oz vs HK as an example). Hasn’t done them too many favours there, has it ?
