The expression "worth your/its salt" is used to describe someone or something that is valuable or effective in their job or task. The phrase originates from ancient times when salt was a valuable commodity and used as payment for soldiers. If someone was "worth their salt," it meant they were a skilled and capable soldier who deserved to be paid in salt. Nowadays, the expression is used more broadly to describe anyone who is skilled, capable, or reliable in their job or task. For example, you could say, "John is a great manager, he's worth his salt," meaning that he's good at his job and deserves to be recognized for it.
