I don't expect any rush in getting this sorted. Cx don't want to hire any pilots ex KA or anyone else at the moment and still have too many of their own pilots. I expect those with expired work-permits to be Sent home on zero pay basically stood down until further notice. This situation actually works well for cx currently.
In the longer term maybe expect to see some redundant pilots offered interviews and a few perhaps one or two positions with HKE as they ramp up to smooth over the waters with immigration.
