It's no surprise la. Maybe for those new are shocked of the sudden reorg.
But news already know few months prior.

And internally people already know this like 1 or 2 years ago.
They have made informal preparation. Already appoint people for the new potion etc. Get them ready etc.
Just that officially their title haven't change.

So previously if you see your M2 now suddenly become AVP is that M2 was already doing AVP work for 1@or 2 years but never got the promotion. Now officially he only got the title change.

Call it a probation. The top here like to try people out for sizes one.
You go observe la you see which M2 in your division started to be in Cc list or starting to shadow or cover the head. You'll know he is up for promotion next...

But that promotion takes 2 to 3 years in the making... That's why only those 20 heads etc get promoted.
This new generation now expects come out fresh high pay. Work 1 year expect to be promoted to senior engineer. Then work 2 years expect to be M1 assistant principal engineer. Then work 3 years expect to be principal engineer M2.

But you all never know your M2 work the same title for the like past 5 years now only finally become AVP.
And you all not happy...

Kids nowadays.
