in an optimal setting, employer should pay according to market rate. ie. manager should get this much, supervisor get this much, etc.

but in malaysia, many employers look at current salary, give a 15-20% hike if they're generous, and negotiate from there.

the positions are secondary, if your salary bracket falls under 'manager', they'll give you the manager position.

that's right, in Malaysia employers look at your current pay and decide on your comp package.

haha if thats the case he's one of the lucky ones..
most people don't get their expected

Could be due to the work environment, issues with reporting managers etc. I have some colleagues who quit due to those reasons.
