Sorry, A330ETOPS, but the relevant phrase that springs to mind here for the deep ops is "!!!! or get off the pot".
If some of the people working there can't hack it, then they're doing absolutely the right thing by stepping back and saying so - but I challenge you to find a single one of them who says that this work should stop just because it's too much for them...
<conjecture>A330ETOPS has not lost any loved one(s) in uncertain circumstances and/or where A330ETOPS would like or need their body(ies) to be interred, cremated, sanctified or, in some other way, put to rest but this was not possible. </>
