What is the difference between 向来, 一直, and 总是?
They do all carry the "always" meaning, but each provide different finer details.


向来 = always; (since the beginning)
一直 = always; (have been continuously)
总是 = always; (unexceptionally /universally)


Examples:

向來沒有加班費  "without overtime pay since the beginning."

一直沒有加班費  "have been continuously without overtime pay."

總是沒有加班費  "unexceptionally without overtime pay ."
