Memo
To: All full-time employees
From: Li Ming, Administration Manager
Date: Oct. 9, 2020
Subject: A computer course
An investigation conducted by the HR Department last month reveals the fact that a high rate computer illiteracy leads to low office efficiency of our company. As a result, it has been decided that all full-time employees are to attend a computer course—which will take place every Monday night from 18:00 to 20:00 in the Meeting Room A and B—for the duration of two months. Employees can sign up for the basic or advanced levels of the course according to the present computer skill. Please register for the course at the company’s reception desk before Oct.15. Further suggestions will be appreciated so that the program can be more fruitful.。
