shape up or ship out
Meaning
Improve your performance/behavior quickly, or leave (or be removed) from the job/team.
Origin
Popularized in U.S. Navy/Marine contexts where "ship out" meant to depart on a ship; figuratively, it became a blunt ultimatum in workplaces: improve (“shape up”) or leave (“ship out”).
Notes
A harsh ultimatum, often from someone in authority (boss/coach). Can sound confrontational; use with care outside strict workplace/team contexts.
