It's not the work these Ukrainian women are doing that matters, nor the wealth of their employers. It's whether they are being treated with compassion and respect, whether they are being paid a reasonable wages and provided with safe, secure accommodation, whether they are being supported in learning English, integrating in the UK and maintaining connections with their compatriots and their Ukrainian identity. And given the opportunity to move on when they are ready. That's what matters.
For 10-15 years my parents were involved with an organisation that rescued traffficked or enslaved women, mostly from the Phillipines. These women were refugees from the most appalling abuse, who took the chance to run away with nothing - not even shoes, sometimes. My parents would take one in at a time, give her a comfortable room with a door that she could lock and we could not, give her employment and an income, treat her with respect and take her to whatever appointments she needed. And helped her maintain her connections with the Philipino community. Yes, she worked as a maid - but we (the teen and adult children) we're not allowed to tell her what to do nor make work for her. We were expected to interact and converse and treat her like anybody else staying in our house.
After a few months or years, each of them moved on once she was ready to do so. I remember one had taken a hairdressing qualification while with us, got a job at a salon and a flat share with a friend.
These ladies kept in touch with my parents for years afterwards. Invited them to weddings and christenings, and to Leave toRemain parties and Citizenship parties.
I do not think helping these distressed women regain their dignity was in any way virtue-signalling or inappropriate. And they clearly did not think so, either.
It's not about what these women do, it's about how they are treated.
