Genuinely don't know if I am BU here and also heartless so please be frank. we have a nanny who looks after our baby 4 days a week. She started in late February this year. Since then, she has taken 10 sick days for things like headaches/ stomach aches. today it was for a swollen insect bite on her foot (she texted me a photo- it looked uncomfortable but the kind of thing that I would have definitely stuck on a pair of flip flops and gone to work.) She has also had two days off for car trouble/ break downs. She also gave me two weeks notice that she was taking the entire month of July off to care for her grandmother after she had an operation, leaving me no time to find a replacement. She is also regularly 10 sometimes 15 mintues late, which amounts to around 3 hours a month, sometimes more. I have spoken to her about this, and it got a bit better, but still happens regularly. I work freelance so I can be more flexible than if I had say, an office job but I still really need the childcare, and also often schedule meetings etc which i then have to cancel.
This morning I told her I was concerned about the number of sick days and late days and said I really needed someone that I could rely on. SHe replied that she was committed, but these things were unpredictable/ out of her control. AIBU to be annoyed/ to say something or am I being totally heartless? (I pay her for sick days, but more worried about the lack of reliability than the money.)
