What steps should Laverne now take with each supervisor to ensure that he or she improves employee performance in each respective unit?

Just thirty days ago, Laverne Wilson was excited when she started her new position as executive housekeeper at the spectacular Melrose Hotel. The Melrose had enticed her away from a competing property with the promise of higher pay, greater prestige, and, of course, more responsibility. With her eye for detail, however, Laverne immediately noticed major housekeeping oversights at the hotel. In fact, on her first day at the Melrose, she was greeted by an overflowing trash can near the main entrance and cigarette butts on the lobby floor.
As Laverne reviewed guest comment cards and the results from guest satisfaction surveys, the problems seemed to multiply. Guest complaints ranged from stained linens to crumpled and soiled stationery in the guestrooms. Worst of all, guest property had been reported missing from rooms on a number of separate occasions, without resolution. To top it off, guest satisfaction reports over the last six months showed consistently low ratings for the housekeeping department and its services.
