Many years ago, workmen used to own their own tools and carry them with them, normally in a bag or sack, from job to job. When they started in a particular job, they would give their tools to the employer. Then, if the worker was no longer needed, he would quite literally be given his sack of tools and asked to leave.
EXAMPLE SENTENCE / FRASE ILUSTRATIVA
Harry got the sack after he was found guilty of theft.
Le dieron cran a Harry cuando encontraron que robaba.
