There is one simple division in SIA, Singaporean and none Singaporean( deemed "others" who get a F.I.N number). All none Singaporeans are then graded in to
PR and none
PR. These are then further graded into compliant, none compliant and finally Malaysian. Malaysians who dont apply for full citezenship are truly at the bottom of the bucket.
As for errr, caucasian expats (the whiteys), they are graded into compliant and none compliant. As in SARS, expect the none compliant guys (ie those who take extra fuel or dont attend fleet meetings or forget to address all local captains as "CAPTAIN" etc) to be first to not be renewed.
I know of one B777 white training captain who has not been "let Go Lah".
As for the locals, they of course achieve very high standards in their base checks, and therefore are deemed to be more meritoricious than a similar positioned expat, and therefore untouchable.
Yes, there is a DAC incident, so that makes 2 GPWS violations of late. Go Figure. Latest cullings in the expat ranks to be 132 from the LHS.
How is that seniority system in SQ
. Dont expect ANYTHING if you are on contract.
