With ipf of 4.07 I got C band despite of so much work ,what can I do in such case?

same case brother.. They don't care. Reject the band and lets see.

I got C band last year on 4.55 rating that also my first C band on last 7 year

Just fuck the work

Yes look for other jobs but the market is not good right now and 90 days NP is a headache

Resign is an option
