Welcome to Indonesia, skill is doesn't matter with your salary. They look for the fahking scroll.

Well. What is your background? A person holding a masters degree will of cause earn a better salary than someone with no degree?

Actually how long you are at a company has very little to say regarding your compensation in the private sector. Only places like government or public offices gives you a raise based on that!

If money is what drives you, take this advice:

Change work often! Like every 1-2 years or so! That way, you will always know your exact market value, and be in a better position negotiating your salary and benefits. Make a detailed plan of your career, and stick to it! Don't get emotionally involved with companies or coworkers... and apply to new interesting jobs often. Even if you have no intention on accepting a job offer.

@anon81 surely thanks, but I more prefer to become an internet marketer

I'm not sure what you mean? The advice applies to every profession in tech or business in general

I like fahking more ... will use it all the time

@anon81 : I will resign for 4 months, because that problems. I code for money and my passion, but now I need money first. So soon I will become an internet marketer, and work alone all by my self. No more degree.

@sam9669 : It's more fahking good right?

Still NOT sure what you mean...!?

Actually there has been done research on how often you should change your job to maximize your income.
Quintessence is, change often but not to often. If you change every one or two years company's will soon notice that it isn't worth to set you up in important projects because you're likely to leave soon. On the other hand job changes - intra-company - gets you the better raises.
So if I remember it correctly in Western Europe the optimum was around a change every five year.

Of course this doesn't hold for freelancers, founders and sometimes trainees ;)
