Hi Andy: I myself have an OML. I have thrashed this subject to death as I hear about more and more colleagues coming across it, unfortunately.
My research over 7 years of heavy discussions with the insurance and aviation industries suggests that someone starting off with an OML is almost always impossible to employ.
This is mainly due to a duty of care issue - putting you in harms way when they or you for that matter don't need to do that and secondly because there is always someone else who doesn't have an OML.
It's a painful fact of reality even though it could be classified as discrimination but we are talking real world here and not some theoretical HR hype.
The traversty is that an established pilot could get a flying job with an OML dependent on their circumstances and that part of the industry they are currently in (Airlines/corporate/Instructing etc). But a newbie wouldn't be touched with a barge pole.
Sorry to be the harbinger of bad news........
