No difference if you are swee char boh and a sinkie. FTsh will step in to replace you since it is common practice for foreign owned companies in SG to discriminate against sinkies to offer jobs to their country men.
Back in my old working days....in the organisation we worked in, we had one, who joined us only for a few months, who was just a typist from the typing pool...who got promoted to sales manager.....she 'played mahjong' & sang " oh soh loh meo" with the bosses 'watering holes"....wore, 'encouraging' clothing to work, salary jumped from $600 ( back then) to $2,000 ( now would have been $5,000), only possess a GCE O Level Cert.
It proves that you must have the "nuts" & "holes" & a pretty face to get promoted fast... ha ha ha ha
