The term "re-signing" refers to the act of signing for another term, most commonly used in business contracts, sports contracts, and employment contracts. The opposite or antonym of re-signing can vary depending on the context but can be understood as refusing to sign again, not renewing, or terminating. For example, in the context of employment, the antonym of re-signing can be quitting, retiring, or being terminated. In the context of sports contracts, the antonym can be leaving, transferring, or free agency. The opposite of re-signing ultimately depends on the nature of the contract or agreement and the reason for the non-renewal.
