answer: Jessica tells Mr. White she'll be leaving because she's been offered another job. Mr. White feels sorry but is willing to write a recommendation letter for her.
documents: #Person1#: Mr. White, I would like to give you notice that I will be leaving the company. It will be effective at the beginning of the next month.
  #Person2#: Jessica, I am very sorry to hear that. Why are you leaving?
  #Person1#: I've been offered another job with higher salary. And it also gives me the opportunity of promotion.
  #Person2#: Oh. If you had talked to me first, we would have given you a raise.
  #Person1#: You are really a good employer, Mr. White and I am very lucky to have such a good boss like you. But this new job is more in my field of interest training. It's something I have always wanted.
  #Person2#: Ok, good luck, Jessica. By the way, if you ever need a letter of recommendation, I would be happy to write one for you.
