Cost saving is the MAIN reason especially if the FOREIGN employee has family n kids which the company has to pay for rental / schooling / home return holiday flights yearly etc it all adds up $$$$ why pay so much when a local person whos salary will be lower than the Foreigner can sort of do the same job but cost a HELL OF LOT LESS!!!
Interesting, what industry are we talking about?Foreigners salary is preety much same as local and several times it is even less if guys just arrive in HK.
