Abstract:
Corruption is like cancer that has been damaging business, society, and the country for a long time. There are three main factors provoking corruptions; individuals dishonesty, organizational carelessness allowing opportunities for those misconducts, and individuals motive due to the need of money. Dishonesty and motive are beyond the organizations control. The guidelines for preventing corruption effectively are, therefore, needed so as not to allow the
opportunities for such crimes. The population of this study was the internal auditor which were members of The Institute of Internal Auditors of Thailand. Questionnaires were used to collect the data. Descriptive and referential statistics were used to analyze the data.
It was found that most corruptions, specifically cash embezzlements, were committed by the operational employees in the procurement units. The loss caused by such corruptions was about 1-2 percent of the total sale. Most corruptions were committed in October-December. Just one employee convicted the crime without any conspiracy. The causes of the embezzlement were employees luxurious expenses and organizations lack of precise control system.
The first five corruptions ranked as frequently committed were procuring with mutual consent or taking bribery, not handing the money to the companies after collecting from customers, using companies vehicles for personal purposes, petty cash keepers using the money for personal purposes, and spending working time on doing personal business respectively. The suggested guidelines for preventing such behaviors were arranging bidding procurements, asking customers to pay with check, having responsible authority to give permission for each use of vehicles, randomly checking the petty cash, and periodically assessing employees performance.
Three guidelines for preventing corruptions in industrial business which were statistically significant at the level of .05 were one on taking merchandises in the smaller number than ordered or in a low quality, another one on faking total sale for rewards, and the other one on reimbursing the petrol expenses using the receipts that were not for the organizations business.""
