Yes, you can get a new job. They probably can’t afford good childcare any more.

What they’re doing is legal and 10% is generous.
What were your hours when you started and what are they now? Them
Dropping hours doesn’t seem fair but you are also welcome to look for something with more hours.

What is your hourly pay rate

People are cheap!

I'd leave for more hours.
Put yourself first.

Nanny.

Yes, that's fair and standard. Nannies are hourly employees per the FLSA and can't be salaried. So giving you a raise on your hourly rate is expected. I'm assuming they did it in hopes of offsetting the reduction of hours. If the lessening of hours means that overall annualized pay no longer is feasible for you, time to start looking for a supplemental PT job or new FT one. Best of luck!

So I am currently on 30k and I have been told I am due a pay rise. They offer me a 10% pay rise but apply it to my hourly wage and not my annual wage, so due to my hours being dropped even with the pay rise I am now on just under 30k?? I would've never anticipated a pay rise resulting in less money than what I was getting before due to the drop in hours which i have tried to counter back and offer cleaning etc just to keep my hours up as I have bills to pay too. I don't think that is right what are your thoughts ?
