There has to be one or two bitter, unprofessional nannies replying multiple times to threads lately, these responses are just too much.
No OP, it is not rude. The nanny hasn't "turned up to help you", you do not need to give her face-to-face instructions everyday (seriously, any other thread and the nannies would be up your a$$ for micromanaging), you are not self-important just because you don't leave your work day to disrupt your child's routine daily to say "hello".
Don't we hear all the time on here that WAH parents need to be never seen nor heard? Yet when the opportunity to bash an employer comes up, the harpies are poised with every insult they can think of?
Like PP stated, it would not occur to most rational adults to be offended, let alone notice, your lack of daily greeting.
