But you are not working for free. You are still well paid.
It is your choice if you want to send your DC to nursery, or delay promotion till they are in school etc. When DC goes to school, you will be quids in.
The title of your thread is " Resentment at 100K"
And many posters here, inc me, have said it's not resentment for people being paid well, it's that we are not keen on the " Pull your bootstraps up" brigade.
Honestly, I hope you go on and get your promotions, and end up as a research director on half a mil a year.
Is that not your incentive ?
Child care is only for a few years. Can't you just take the hit for a while, like everyone else ?
And for me, I am thinking forward a bit, a thought experiment.
Daily Mirror headline. " Single parent on 110k claims 22k in benefits". !
Apologies by the way for my lack of GBP sign on my posts in your thread. US keyboard and can't remember the code. Ahh wait £. Alt 0163. I really should write down :-)
