I lived in England for many years and many families would hire Filipino nannies because they are so hardworking, and were relatively cheap compared to their English counterparts. I would get quite a few Filipino nannies in the baby development classes that I ran, and many of them were mothers themselves with children in the Phillipines who came to earn some money to educate their children. They came freely, of their own accord. I did not witness or suspect any form of human trafficking, but,that’s not to say there isn’t any… The free housing and food YWee mentioned means they can send a large proportion of their money home where it makes a huge difference to their families. Filipino nannies are also good at recommending or bringing replacements when they decide it’s time to leave – often a relative, and so you can enjoy many years of continuous service from them.
