I dont want 延强 to work with you. Last time, he worked with you for one month and two weeks. First, you said you will give him 200 a day. Second, you changed your mind to give him 100 because you said he's very lazy. Then until now you still no give his previous salary. He wasted one month and two weeks not giving him a good salary, and now you want to work with him. You should give his previous salary before he can work with you again.
