My understanding is you have to tell them as soon as you start working.... but having said that, if you need to do job searching between now and then you may want to tell them sooner and see if you have to continue looking for work or not...

I guess there are pros and cons both ways - but my understanding is that they don't cut your payments off before you start work - I've had unemployment benefits 3 times and each time I continued to be paid until I started working. I don't remembr when I told them though. I think it was the week I started.

As long as you tell them ASAP after you start you should be okay though. I'm pretty sure they will cut it off as per the date you start working. Depending on when you get paid at the job, you may have a little gap - hopefully not too long for you!

BTW - congrats well done and good luck!!
