I'm currently thinking of a career change. Hence, seeking advise here.

Joined civil service in 2009. And am wondering about my career progression.
Here's my increment details.
Oct 2009: 2,350 (drawing a lower pay due to economic recession)
Jun 2010: 2,500 (adjust back to market level)
Oct 2010: 2,900
2011: 3,300
2012: 3,600
2013: 4,000


With the completion of my big project, I was not entitled to an A nor any promotion as my director was bias and favour only those with qualification of at least second upper.I did not graduate with honours. I've to be sacrificed year after year despite contributing and performing well, due to my qualification.

I was wondering should I resign and join the Stats board after drawing my bonus next year. Am looking for an AD position or mid-level post. Im wondering if i can demand for a 10-20% pay increment in a stats board? Also, for future career advancement within civil svc, was wondering if i shld further obtain a masters.

Anyone with good advice or similar experience to share?
