Get the sack is an informal British English idiom that means to be fired or to be dismissed from a job. If someone gets the sack, their employer decides that they can no longer keep that job.
The most common explanation for the phrase is historical. In the past, some workers carried their tools or belongings in a sack. When their work ended, especially if they were dismissed, they would take their sack and leave. That physical act likely helped create the modern expression.
Today, people use it figuratively. No actual sack is involved. The phrase simply refers to losing a job, often because of poor performance, bad behavior, or business problems.
- He got the sack after repeatedly arriving late.
- She was worried she might get the sack if the mistake was serious.
This idiom is common in everyday conversation and news style writing in British English. In American English, people more often say get fired or be fired.
