I think if you write something which says 'I am biased', the burden of proof is now on you to show hiring managers that it was all a bit, rather than on them to demonstrate that it wasn't.
This feels like an unreasonable expectation for the people who would be reporting to him.
If someone in your future/present management chain wrote a "I think people like slibhb are bad at this job" missive somewhere, would you then feel the need to wait for examples of bias?
