I've been childminding for 2 month now and my main income signed a contract to pay monthly. Then mam asked if she could pay weekly so I agreed as long as I'm paid I'm happy.

That was 3 weeks ago and I haven't yet been paid. I keep asking them for payment but no joy so far.

I have decided that if I don't get paid tomorrow I won't be providing hold are for them until I do.

How do I word this without sounding petulant?
