One important advantage the CS has over other tech firms, MNC etc is the stability it offers
Have anyone ever heard of retrenchment in the CS? Or the need to let go of ppl because of re-organisation (eg: shifting of HQ to other countries?). Moreover, the pay will only increase for CS over your length of service. It is unlikely that you will get a pay-cut (unless you get a demotion due to verrrry serious offence committed). This stability will only get more valuable as you age (where in the pte sector you risk getting replaced due to you being old and expensive). So, if the CS package is decent and comparable to the tech firms, MNCs etc but just losing out on things like business class travel for.overseas work trip, I am prepared to choose CS anytime. Haha. If you are capable enough to reach superscale grade in CS, you get the pay, fringe benefits and stability all at the same time.
