Cactus,
I've worked for both of the A320 LCCs that operate in Australia. I'd have to say that what your 'close relative' has told you should be taken as a load of rubbish.
These are airlines whose CPs are far too busy to bother themselves with contacting line pilots over insignificant operational matters; perhaps they might for an 'incident' that could come close to being a significant and negative one for the company. But for a go-around? And on '...numerous other occasions...' for '...MEL...' matters??? I find that impossible to believe. Especially as I personally know all the men who have/do hold that office with those airlines.
They have far more important things to occupy their day, than to worry about that kind of drivel.
No manager in either company, let alone the CP, has ever contacted me for committing either of the atrocities that you mentioned.
But, hell, let's not let the truth get in the way of a good yarn.
As for the answer to your last question; there are only a few people who honestly know whether he has or hasn't been 'pineappled' (as you so delicately put it) - they are the PIC, the CP and whoever else happened to be present when any discussions were had between the two of them in relation to the matters concerned. Anyone else is peddling hearsay. Pure and simple.
