When you say "the end of the day" in a work situation, it means 5:00, 6:00, or whatever time most people leave work.

This is something you would say if a coworker is going to make a proposal to a client, but she is supposed to ask Henry, who's the Director, for permission first.

Remember to get Henry's approval before you present it to the client. Tell Jill that Ill get back to her on that business proposal after the weekend. Instead, it's used when you need to do things in a certain order: To communicate with someone at a later time or date regarding a specific issue. "Before" is similar in meaning to "by", but "before" doesn't carry the same meaning of "deadline". We're presenting this on Monday morning, so remember to get Henry's approval by Friday afternoon. You use the word "by" to indicate a deadline. I don't know off the top of my head, but I'll get back to you this afternoon. For example, if you ask me a question and I don't know the answer, I can say: To "get back to" someone means to respond to their question later. If you could get back to me by the end of the day, that would be appreciated.
