I have a query that I can't seem to find any guidance on (or I haven't looked hard enough). But basically, we have had a certified FLT instructor give FLT training last week. One of our employees were deemed too unsafe to pass and obtain a certification. The instructor said that they may pass if they retook the course.
Now, my question is, would this come back to bite us on the ass if we put him back through the course, they pass and then have a major accident down the road. As, we've already identified that they cannot use the equipment safely surely that would be a negative for the company? Or, is it that because we put him through training again we can assume that this person is competent?
Or the instructor is trying to get some more money out of us!

Any thoughts on this would be appreciated (apologies for any mistakes, I've just got into the office)...
