From: Brent Watson <bvvatson@dixon-solutions.com>To: Marketing Staff <markelingstaff@dixon-solutions.com>Date: October 12Subject: New OfficeTo all staff members,You may have observed that the demand for our department’s services has increased substantially over the last two quarters. — [ l ] —. As a result, we have had to double our workforce. Unfortunately, the addition of staff has not produced the expected increase in productivity. — [2]—.After studying the problem, I have found the cause to be a lack of adequate facilities. I raised the issue with upper management and am happy to announce that during last week’s meeting, the board approved a proposal to move our offices to a larger space on the eighth floor of the building. The new office will come with fully equipped workstations for everyone. — [3]—.Renovations on the eighth floor are expected to begin at the end of this month and last through November. In the meantime, some of us will begin working out of a temporary office space on the third floor.I appreciate your understanding. 一 [4] —. Please let me know if you have any questions.Sincerely,Brent Watson Marketing director
