Jump ship
"Jump ship" is an idiomatic expression that originated from maritime terminology. It refers to the act of leaving a difficult or failing situation, often abruptly and without warning, much like abandoning a sinking ship. Metaphorically, it describes the decision to abandon a job, project, or organization that is experiencing problems or is expected to fail. This action is typically taken to avoid being adversely affected by the situation or to seek better opportunities elsewhere before the situation worsens.
The phrase implies a sense of urgency or necessity in leaving, suggesting that remaining in the current situation is no longer viable or advantageous. It can also convey a lack of loyalty or commitment, as it involves abandoning responsibilities or obligations in favor of personal gain or safety. "Jumping ship" can be seen as a pragmatic decision to protect one's interests or to pursue better prospects, even if it means leaving behind colleagues, teammates, or responsibilities in the process.
