I saw some lyn member only 28-30 earn the same salary as you.

Probably you should try find other private company which offer better paid & bonus then stay in government sector for the rest of your career.

Now 6-7k is nothing for a family person. With that salary can't even afford to buy a 500-700k double storey.

You're wrong.

With that salary by age 55 of retirement he will have 10k++ plus, with every year increment.

Pension will be half of his salary. Private sector in malaysia salary are still stagnant within 5k - 7k for senior level and has not yet growth to 10k at staff level, unless you are really specialized in a skill set.

He will be earning the same salary scale in private sector as well. I wouldn't quit government unless was offered 15k++ stable, routine and good beneficial job since  same like the government and most government work are pretty much a routine job with being a family guy it is a plus.

Wow, seriously audit firm senior manager earn less then you? A small medium size firm? Guess it is typical case for audit firm to underpaid the staffs.

I'm an Accountant in MNC with 5yrs experience, just earn slightly lower then you. Guess your Bro. is seriously underpaid for that position & experience. (there have few vacancies in my company, if don't mind can PM me) 

But to get a 100% jump to 15k, it rarely happen lah, unless you have special skill/experience rare in the market that the company desperate need it.

IMO, that not underpaid... the matter is are you good in controlling your financial.. 

YOu are doing good than most ppl
