Dangly,
Quite a few have had to attend, (I know 2 personally) one chap off my group was involved in a certain high profile case, agitated by a well known fellow. He did nothing wrong, everything in accordance with the 'rules of the day'
If the system is broken and you know it, you can't decide to non-comply, doesn't work that way unfortunately. 4 or 5 years later my colleague is not back on the console. A good operator tainted by our agitator who would have been better served attacking the system, not the operator.
And that threat IS there everyday. No different to a pilots legal responsibility really.
