We expect our corporate members to use audits as a way of diagnosing problems, not as a ‘pass or fail' test. In fact, it's very rare to find any company that's fully compliant with the Base Code.
If you supply an ETI member company, you should expect them to help you make any necessary improvements within a timeframe that works for both of you. ETI member companies should not stop trading with you if the audit uncovers only minor issues. However, if they uncover very serious issues, you will be expected to take immediate corrective action. If you do not do so, you may lose the business.
