You’ve hired a housekeeper but want/need are treating her as a cleaner.
I know you levelled with her at interview, but in reality, she’s poss unhappy? Usually HKs have a broader spec & even in a house your size will have a cleaner to manage for the grunt work approx x1 a week or x2 a week, for a few hours.
Good HKs are skilled professionals who take a real pride in their work. What were her previous responsibilities/duties? She’s underutilised. Why pay that salary for a cleaner? I would expect:
Some cooking & organising/shopping for food. Simple meals & salads/low cal snacks made & in fridge for me. Playdate pasta cooking, or similar.
Dry cleaning responsibilities.
Running errands - post office, picking up items, making appointments at opticians, etc.
Looking at spreadsheet re: scheduling spring cleaning, ditto: upholstery, carpets, curtains, as appropriate.
Helping with wardrobe management. Charity shop run, etc.
Picking kids up from school sometimes, supervising homework if appropriate.
Animal care - vet runs, etc.
Managing tradesmen & keeping on top of deliveries. Etc.
Helping to manage any interior design projects.
Helping declutter & with filing if appropriate.
If kids 6 ish plus, keeping an eye on them if you need to go out sometimes/relieving nanny if you have etc.
Friendly, kind, caring upbeat disposition.
House ‘visitor ready’ at all times.
That’s what 45k is for.
Do you have a contract/job spec? Did you hire her through an agency?
