You don't want to clean toilets for $12 an hour but that doesn't mean you should be telling those that do that they should not be accepting those conditions!
Individual Choice
Mate that is where you are wrong.. individually nothing is acheived!!!...
But in the meantime it couldnt hurt for you to suggest that youll clean the toilets on a turn around for $12.. the cabin crew probably get paid $13.. management will love you!! but hey its your choice!!!!.. just dont miss that spot behind the bowl!! and wash your hands!
