A、The shift among employees. B、Good office relations. C、Improved staff attitude toward the work. D、The new record-keeping system

M: Please come in, Miss Edwards, and close the door behind you.
W: All right.
M: Have a seat over here. How are things going out in the office?
W: Just fine, Mr. Davis, especially with the recent personnel shifts.
M: Yes, I thought so. Well, I and the executive board feel that much of our improved performance in the main office is due to your hard work.
W: Oh, thank you, Mr. Davis. My job has certainly become easier since we computerized our recordkeeping system. The equipment is a pleasure to use.
M: That’s true. But we are especially impressed with how your influence contributes to good office relations and improved staff attitude toward the work.
W: Well, thank you. We do have a lot of good people in the office, and the new machinery is wonderful.
M: Yes, but machines are only as good as the people who use them. They cannot assure harmony and efficiency in a staff.
W: That’s very true.
M: To make a long story short, the board wishes to reward your efforts by making you office manager next Monday. That means a $250 raise next month.
W: I’m deeply honored, Mr. Davis. Thank you.
