4Check contractors' performance records

• Monitor and evaluate the performance of contractors regularly and immediately after the contract has ended, and ensure that the evaluation is properly recorded for reference in future tenders.

• Maintain periodical contacts with suppliers or contractors in order to provide a direct channel for them to express views and grievances. It is better if these contacts are initiated by senior staff.

• Inform suppliers and contractors of the company's policy of prohibiting staff from engaging in corruption or other forms of malpractice.
