ate: Friday, March 28 Subject: Your new office Dear Mr. Saito, Im writing to let you know that you are going to take over Trevor Jacksons old office and phone number(3256), as he has taken an extended leave from work. Unfortunately, customers have not been informed about this change, and consequently, you might receive many calls from his clients. So, we will be changing the extension number on the employee directory as soon as possible, and connecting your previous extension number(3605)to room 320. Our facility team will be redecorating your new office by the end of this week. On April 1, you are welcome to visit the new office to become acquainted with the interior. I hope you resume work without any problems. Feel free to contact me if you need further details. Thank you. Susan
