I'm in favour, there's no room for influence of drugs, including alcohol in our business.
I saw an aircraft destroyed once after an alcoholic senior manager made a seriously bad decision one afternoon after a long lunchbreak in the pub. Thankfully nobody killed and the aircraft was insured, but it was a hell of a close call.
If anybody wants to test me at work they're welcome, I'd just be grateful if they'd stick to a urine test - I'm terrified of needles!
