This won't happen one. Cos they need to have disparity between poor and good performers to maintain the competitiveness and productivity. If ppl chiong to get good grades and they get these kind of bonus compared to a D grader getting 0, nobody will perform anymore.

If first year default C then probably between 1.25 to 2. Usually 1.5

There is a percentage cut (less than 10%) for PB across the board.

Will promotion raise and merit increment be cut?

Maybe. If so, just too bad for those who promote or get a good grade this time round. It will leave a lifelong disadvantage since subsequent increments would take into account the last drawn.

hope u are right. 10% is reasonable for this climate. and the remaining 90% is still good

so a C grader will probably get 1-1.25 mth next Mar?

a C grader at mx13 will be in this range.
the higher grade u are, the more bonus.

You are stating this as a fact. As such, I would like to know first before sharing with my colleagues, what is your source?

u must be crazy to spread such rumour from an anonymous on the internet forum
