CART EX,
I didnt say the majority of senior crew are lazy and negative , I gave a conservative figure at about 50%, Of course i could be wrong but it is based on 18 years of hearing countless crew (mainly males) brag about how"they dont do toilets", fortunately some have left with recent packages,unfortunately too many still remain. Many of those I refer to seem to have super glued their backsides to the galley seats on night sectors.
Your right it is still preferable and practical to have some sort of request system - but NOT on seniority.
