工人做得好，現要走了，想給她一封推薦信，要如何寫？有沒有sample參考？

僱 主 在 聘 用 新 員 工 時 常 會 要 求 員 工 提 供 推 薦 信 (reference letter) 。 推 薦 信 主 要 由 僱 主 撰 寫 ， 有 些 僱 主 則 會 要 求 員 工 自 行 撰 寫 推 薦 信 供 其 參 考 。
以 下 是 推 薦 信 包 含 的 內 容 ：

第 一 部 份 ： 說 明 推 薦 者 與 你 的 關 係
第 二 部 份 ： 詳 列 你 的 工 作 職 責
第 三 部 份 ： 推 薦 者 對 你 表 現 的 評 語
第 四 部 份 ： 推 薦 者 對 你 的 支 持 及 能 力 的 確 認

To Whom It May Concern
It has been a great pleasure for me to work with Ms. Cheng Lok Yiu, who has been a marketing officer with our company between the year 1999 and 2003.
As a marketing officer of our company, Ms. Cheng is responsible for a number of job duties ranging from promoting our company products, exploring and establishing business relationship with potential clients.
Apart from being a good team member, Ms. Cheng also displayed considerable initiative and approached her work thoughtfully and intelligently. Ms. Cheng also impressed me of being able to rise above the call of duty on certain occasions and was more than capable of taking up extra responsibilities.
Your favorable consideration and assistance to Ms. Cheng will be very much appreciated.

Yours faithfully,

Agnes Chow
Head
Marketing Department
