My domestic works for us three times a week, and I trust her with my home. She has keys. She has access to all my valuables and personal items. It really does not get more personal than that. She looks after my animals when I am away, and will do certain things for me around the house. She is an important part of my family's life as without her I wouldn't have the time to pursue anything else. She has been with us for 8 years, and in that time she has stolen nothing, she has not caused any large financial losses, and she treats our animals and home as she would treat her own. That type of person is someone you treat well, and not keep at an arm's length as you would a regular employee.
You are a bachelor? I have a big home with animals and other beings staying there, so my needs are different. You are willing to accept the risk of having strangers in your home, I am not. Especially not in this country.
