Which is why I didn't request a number.

I kept telling them - just pay me the market rate for the role.

I am paid relatively well currently - but throwing my pay slip only stops my growth (20-30% increment max)

Why limit yourself? Let them decide what they should pay you.

In my current company I am doing well and all settled, I have built a good name with the management here.

For 20-30% increment, I have to go to a totally new place (smaller company than my current company actually), work hard and build my name all over again - it’s not worth it for me.

I haven't been in your exact situation, but I've been in a similar one.

I lost a job opportunity with 200% increment after providing my pay slip even though the hiring manager and HOD were both keen on me.

Then I got an even better offer with 300% increment without providing my pay slip.

Moral of the story? There isn't one! Just be selfish and keep job hopping. Screw the dumb HR people who can't attract nor retain good talent, yet keep lowballing and wonder why good talent is so hard to find or keep.

Take control of your own career. If you don't, HR will.
