you have been a boss 和 you were a boss 什么区别？

have been是现在完成进行时，
you have been a boss是说你已经是一个老板了，而且目前也还是老板。
were 是过去式
you were a boss是说你过去是一个老板，但是现在已经不是了。

区别在于你前后想要表达的意思，你是想说现在的事情还是在说以前的事情。
you have been a boss, you should know how this is gonna work. 过去当过头，现在怎么做
you were a boss, you had to try to keep the company running. 完全在谈论过去
