minimum turnover and cost. The study was initiated because of the very high turnover rate of cleaning staff and the substandard work carried out. To further exacerbate management's situation, the hiring, training, outfitting, and maintenance of a housekeeping staff is one of the largest budget line items for most hotel/motel operations. During the assessment it was discovered that a standard of cleanliness had not been established, feedback to the cleaning staff was essentially nonexistent, and aversive managerial practices were common, leading to low morale. The applications of behavior modification began by establishing clear standards that could be objectively measured regarding cleanliness. Management then chose to positively reinforce the role of the cleaning staff by rewarding their performance with merit-pay increases when they adhered to the cleanliness standards set forth. Regular feedback was given to staff to keep them informed of training and expectations. The program was successful in improving worker morale, raising the level of cleanliness, and saving a substantial amount of money in the long term.
