Worth one’s salt: Very worthy either because he has a good character or because he is a competent and valuable worker. Long ago workers were paid wages in salt. In fact, our word salary comes from the Latin word for salt.

值得：很值得，要么因为他有良好的素质，要么因为他是一个有能力和有价值的工人。很久以前，工人的工资是用盐支付的。事实上，我们的薪水一词来源于拉丁词的盐。

That employee doesn’t do anything. He is not worth his salt!该员工没有做任何事情。他不值这个价！
