dittany - not all expats treat their home help like that. DDs nanny lives in our apartment (not in a maid's room, because I wouldn't have made my cat live in there), is paid more than double the "locally accepted wage" for her services, has a contract with set hours and duties, set holiday (4 weeks a year on top of our generous 19 days bank hols), sick pay, medical insurance etc etc - in fact, all of the things I would reasonably expect to provide an employee of similar standing in the UK. She eats at our table when she wants to, but chooses not to most of the time, preferring to go out and eat with her friends (who are all begging me to find them a job like hers).
No, I don't pay her UK minimum wage, but that would be a fortune here - more than senior local executives in my industry, more than teachers, more than doctors. I do pay her enough to support herself, her extended family of about 6 people back in Myanmar, and to save for her future. I also, at her request, pay for her to take classes in English and cooking (the latter for her pleasure, she doesn't cook for us).
She's a refugee from Myanmar, and is only miles away from her family because of the political situation there. Had she not found work in a domestic situation (one of the few jobs open to non-Thais if you aren't hugely highly educated), she would have been sent back across the border. So there would have been no benefit to her if she hadn't found a job doing what she's doing - she would have suffered, so would her family.
I've posted about her before - she's in her situation because of an accident of birth and i have no doubt that had she been lucky enough to be born somewhere with greater opportunities, she would have made so much of herself - she's smart, well-educated and a born achiever. She's with us now, and i see it as part of the deal and, to be honest, a human thing to do to a) make sure we give her oppportunities that she wouldn't otherwise get and b) make sure that she isn't exploited either by us or by anyone else.
Putting lots of noses out of joint here, but I can live with that. Some people here (often British, I'm ashamed to say) should be thoroughly ashamed of how they treat their home help.
