The industry i work for, in Malaysia appreciates B type of people. Which to me is ridiculous. Most jobs are easy and can probably be mastered in 2 years the rest of the 8 years is repeating those 1-2years. If it takes you 10 years to be a master in something which is not technically challenging which very few jobs are...then u are seriously not a capable person to do that job (these goes to engineers also). Question is dont u get bored of doing the same thing year in year out?

I notice this salary slip asking thing happens a lot in malaysia.

By right a salary slip is a P&C document that company gives to you like a resit of payment. Some companies want to keep their  staff salaries a secret from competitors etc.. if you and your vendor had a deal would you like it if the vendor shows your purchase resit to a competitor, or if your tender bid is reveal to your competitor would you want that? Hence the P&C.

Why do you need documents to be private and confidential. In the pay slip case is the same as giving you a level playing field during negotiations. Also you are not supposed to reveal to any collegues(jealousy reason) and the HR is bound by contract/policy not to publicly reveal your salary. If your HR even accidentally slips your salary to a collegue that person will get fired well in most reputable companies. So if your salary is so important to be kept secret within the company why do you reveal it to an outsider?

I dont think you understand what private and confidential means yet.

Simple said if a document is what one stakeholder deems private and confidential and providing enough info to be identified to the stakeholders, then it is P&C. The actions taken by other parties pertaining revealing to a third party is not legal.
