Domestic Helps - Angels or Humans

My grandfather's house (paternal father) in Burnpur covers a total area of 24 catahs, the garden behind the house alone stands upon about 7 catahs of land (some of my short story attempts have been centred around this house). Dadu had a gardener whose wife was the domestic help at the house until she was very old and later her daughter, Umi didi replaced her from a very young age. Umi didi is roughly 55 years old today. All the kids in the house have been extremely fond of her.
I remember following her where she had her lunch and sat through her entire lunch watching her eat the mountain like quantity of rice in utter amazement. She first drilled a hole at the peak of the mountain, poured her daal, then everything else into the hole thus formed and like an active volcano, coloured the rice slopes yellow and brown or green depending upon what she was eating and slowly ate her way towards the base of the rice hill and the edge of the plate. I followed her all around the huge house, to the local fish market, to the aata chakki, to my eldest sister's bungalow nearby. I was, like all the other kids before and after me, very fond of her.
She still works at our house and none of us or the extended family have ever seen her develop any arrogance (or lyaj as we might refer to the attitude in bangla). "The arrogance or Lyaj includes every kind of attrocity you can think of directed to the immediate or the extended family".
At my maternal grandfather's house, in south Kolkata (Mudiali), there was a domestic help, who I addressed as Paban Mama. He grew up there since he was a small child from Sunderbans as a family member. My Dadu educated him and later helped him financially to start off his own business. He started doing well in his business, Dadu helped him move out to begin his own life, he then got married and eventually had two kids. Paban mama, untimely passed on to his eternal abode due to heart attack at about 50 years of age, last year. Never seen him develop arrogance (or lyaj as we might refer to the attitude in bangla). "The arrogance or Lyaj includes every kind of attrocity you can think of directed to the immediate or the extended family".
In case you have employed long term domestic helps, who treat your loved ones bad, may be you should stop, take some time off and ponder on the simple fact that they are all human beings and come with flaws and no matter how trustworthy they have been, may be something is seriously wrong. More so if all your extended family members are also telling you to do the same. Not all domestic helps are good.
Not everyone installs CCTV cameras to check on what they actually do and what they say they do..... "to and with your loved ones."
It is sad that your loved ones have to even ask you to look into it. Or may be your loved ones are mistaken to call themselves your "loved ones".
