CC could do is help rather than PERHAPS standing at the back chin wagging
Problem is that if you injure yourself while stowing bags, no one is gonna pay your sick leave, at least where I work. Since stowing away bags is not on our job description, we are not insured against the injuries that could be caused by stowing away bags. Two years ago a collegue took pity on an old lady with a very heavy carry on baggage and stowed it for her. She injured herself while doing it. Result was that she lost allowances for almost 3 months and she wasn't granted sick leave for an injury while working (which means she got paid less on sick leave) because stowing away bags is not on our job description.
What we do is
help someone stow their baggage but not
do it for them. We'd be in bad shape at the end of the day if we had to lift all the incredibly heavy stuff people carry on board. Passengers still have the option of checking in their heavy luggage if they can't lift it. But if
they cannot lift it, why should
we do it?
