Current trend among the younger workers is to jump, jump, jump. Each jump is a 10-20% raise. The public service is just one of the many employers out there, and these people have options. With reduced recruitment, almost everyone is a scholar nowadays.

Comparing with their friends within the wider public service and in the private sector,. Why stay for a measly 2-3% annual increment if they can follow their friends, jump around for 20% raises every couple of years? I have seen a few math teachers successfully hopping into data scientist or analyst roles in banks and MNCs after finishing their bonds.
