Mr Ho,a supervisior in production line bring me around in the factory to see the workers doing their work in there,the types of works they do are mostly bending the reinforcement bars and attach into the forms.Then at 3pm,we went to the factory to check the reinforment bars before concrete is pour and later found out that a steel bar is missing.Mr Ho is very angry and scold at the workers to redo the work,he said he had no chioce but to scold them because they may heck care and commit the same mistake again.
