"that you're not only worthy of keeping the job, but also why you deserve that 4% raise."

I once 'earned' a 4% raise at a perf review in July. Was then was told because I only started in January that year, my raise - affecting the pay going forward - was prorated to how long I'd worked already, so .. I only get 50% of the 4%, so... 2% raise.

Felt far more manipulative and shady than if I'd just been given a 2% raise.
