I work in an aerospace company (formerly Goodrich Aerostructures, presently under United Tech) and I understand that the Environment, Health & Safety officer in my company commands around $8K. Although she has a Master's degree from NUS, I suspect that her high salary is attributed to the safety related certifications & licenses which she have attained over the years. In fact, such a pay scale is higher or equivalent to some of the managers already, not bad for a lady in her early 30s. Verdict? Study Environmental Engineering in NUS and specialise in this field.
