Earlier quoted context omitted.
Yes, I've seen families in Malaysia and Singapore that really treated their housekeeper badly. In a lot of cases, they are not allowed to go out of the apartment either because of potential pregnancy or because they are scared of the housekeeper stealing things from them. They bring housekeepers from Indonesia and pay them very little. The housekeepers have to work a lot of hours and are pretty much treated as slaves…
I only can speak for malaysia and yes this issue doesn't get brought up much, it's quite sickening to be honest. What is even more interesting is that most of the housekeepers are hired by the middle class, the same middle class that is wants racial equality in malaysia..
I have no issue with people hiring housekeepers but the work conditions absolutely need to be decent. And if for some reason they feel that there's too much risk in being decent, then they shouldn't hire a live in housekeeper, they could also easily hire locals to help with some housework.
Of course, that's not everyone, I have some Malaysian friends who treated their live in housekeeper with respect, let her take some holidays and even helped her set up her own business when she went back to Indonesia. But, that's the exception rather than the norm.
