(pronounced JEH-teh-sehn)

Though this word originally meant to lighten a craft’s (air or sea) load by sacrificing cargo during a period of distress, you can also use it simply to mean to discard or abandon something that is no longer required or desired.

Example: At the beginning of the recession Veronica’s firm lost the two national account clients that had been feeding them seemingly endless retail work for the previous three years, resulting in her agonizingly having to jettison eight employees and 2,000sf of office space.
