And so you should!
If you are genuinely that offended I am surprised, it is clear from this thread and. I guess others like it that the use of a nanny is a hotly discussed subject. Strange though how many of you immediately got defensive about being working mothers and fathers' not getting any grief when that was never referred to.... I have not once stated that this family should jot seek help, but I do still believe their expectations are utterly unrealsitic, unreasonable and illegal. They clearly do not intend to treat their nanny with any love or respect if they cannot be bothered to issue her with a contract, holiday pay or job security do they? 
And yes Mrs Lion, good and experienced, qualified nannies have huge negotiating power, which logically means they will command far more than the £10 per hour we are all going around in circles discussing here! They are seeking Mary Poppins ( for 2 kids) package on ginger beer money and it stinks. To high holy heaven.
That does not mean though that I or other posters resent, dislike or have no respect for those using a nanny. I resent, dislike and have zero respect who attempt to flout the law,pay below a reasonable salary, avoid tax and contractual obligations and still expect a 5* service from somebody they are expecting to become a key part of the family.
