IPA: //ˈɡɪv.bæk//
KK: /ˈgɪvˌbæk/
A reduction in wages or benefits given back by employees, often in response to economic difficulties or in exchange for other advantages.
The workers agreed to a giveback of their bonuses to help the company during the financial crisis.
Giveback → It is formed from "give" (from Old English "giefan", meaning to hand over or grant) and "back" (meaning to return to a previous position). The word "giveback" means to return something that was given or to restore something to its original owner.
Think of the act of 'handing over' ('give') something 'back' to its original place or owner — that's what giveback means.
