Why did Jurgis wait for two hours to see the boss? Chapter 4

Jurgis didn't realize he was supposed to go into the boss' office, so he waited outside the door for two hours.

Promptly at seven the next morning Jurgis reported for work. He came to the door that had been pointed out to him, and there he waited for nearly two hours. The boss had meant for him to enter, but had not said this, and so it was only when on his way out to hire another man that he came upon Jurgis.
